【摘要】：灌區(qū)是農(nóng)業(yè)的命脈，是國民經(jīng)濟(jì)的基礎(chǔ)，是世界以及國家糧食安全的保障。我國灌區(qū)工程大部分始建于建國初期，由于工程設(shè)計(jì)和施工標(biāo)準(zhǔn)低，配套不全，在自然環(huán)境和人為因素的影響下，渠系建筑物的材料性能和受力狀態(tài)不斷變化，加上管理運(yùn)營不當(dāng)，工程老化失修，致使病害發(fā)生、發(fā)展，功能下降，灌區(qū)的渠系建筑物不同程度地都出現(xiàn)了老化病害以及損害現(xiàn)象，部分工程設(shè)施已經(jīng)不能正常發(fā)揮其功能，工程效益受到了極大的影響，國家糧食安全受到了一定程度的威脅。灌區(qū)工程的老化病害以及損害及其帶來的灌溉面積萎縮，已引起了各級(jí)政府和各有關(guān)部門的關(guān)注，國家逐步加大了灌區(qū)加固改造與續(xù)建配套的投入力度，為灌區(qū)渠系建筑物老化病害以及損害治理提供了極好的機(jī)遇。 渠系建筑物安全鑒定，是灌區(qū)可持續(xù)發(fā)展的基礎(chǔ)，是灌區(qū)加固改造與更新改造工作的重要環(huán)節(jié)之一。為確保建設(shè)質(zhì)量和建設(shè)資金的有效使用、提高改造水平和效益、提高灌區(qū)管理水平，必須對(duì)渠系建筑物的老化病害以及損害進(jìn)行全面、系統(tǒng)和科學(xué)的安全性評(píng)價(jià)。主要內(nèi)容及成果如下： （1）修改與完善灌區(qū)渠系建筑物安全鑒定指標(biāo)體系。 以前期研究為基礎(chǔ)，針對(duì)各類渠系建筑物的不同特征，以水力影響因素和結(jié)構(gòu)影響因素為準(zhǔn)則，遵循評(píng)估體系的構(gòu)造與灌區(qū)渠系建筑物的特征相一致的原則，利用層次結(jié)構(gòu)把一個(gè)復(fù)雜的結(jié)構(gòu)分解成若干部件和構(gòu)件的方法，修改和完善了各類渠系建筑物的安全鑒定指標(biāo)體系。 （2）修訂灌區(qū)渠系建筑物安全鑒定標(biāo)準(zhǔn)。 針對(duì)不同的渠系建筑物，以安全鑒定指標(biāo)體系為基礎(chǔ)，根據(jù)實(shí)測值的劃分標(biāo)準(zhǔn)，結(jié)合灌區(qū)的具體情況，對(duì)灌區(qū)渠系建筑物安全鑒定標(biāo)準(zhǔn)進(jìn)行了修訂。 （3）建立三種灌區(qū)渠系建筑物安全鑒定數(shù)學(xué)模型。 運(yùn)用專家評(píng)價(jià)法的原理，通過專家們對(duì)各類渠系建筑物運(yùn)行狀況的現(xiàn)場評(píng)定，建立專家評(píng)價(jià)法模型；以模糊數(shù)學(xué)為工具，利用層次分析法計(jì)算各級(jí)指標(biāo)的權(quán)重，建立模糊綜合評(píng)價(jià)數(shù)學(xué)模型，分別對(duì)灌區(qū)渠系建筑物進(jìn)行定性和定量的安全鑒定。綜合比較兩種方法的優(yōu)缺點(diǎn)，根據(jù)兩種方法的鑒定結(jié)果，采用會(huì)商法，對(duì)灌區(qū)渠系建筑物進(jìn)行最終的鑒定。 （4）安全評(píng)估與分析。 根據(jù)安全鑒定計(jì)算得到的鑒定結(jié)果，按照不同的渠系建筑物進(jìn)行鑒定結(jié)果的統(tǒng)計(jì)分析，各類渠系建筑物統(tǒng)計(jì)內(nèi)容劃分為4個(gè)層次：功能狀態(tài)、結(jié)構(gòu)變形情況、結(jié)構(gòu)破損情況、地基基礎(chǔ)情況，得出灌區(qū)各類渠系建筑物的整體安全狀況。 （5）開發(fā)灌區(qū)渠系建筑物安全鑒定軟件系統(tǒng)。 選用WIN XP中文平臺(tái)為開發(fā)環(huán)境，，采用Visual Basic6.0為前端開發(fā)工具，以桌面數(shù)據(jù)庫系統(tǒng)Access2003為底層數(shù)據(jù)庫平臺(tái)，采用ADO技術(shù)訪問操作數(shù)據(jù)庫，以現(xiàn)今流行的面向?qū)ο蠓椒槌绦蛟O(shè)計(jì)方法，開發(fā)出灌區(qū)渠系建筑物安全鑒定軟件系統(tǒng)。軟件系統(tǒng)主要包含了9個(gè)功能模塊，分別是灌區(qū)基本信息管理模塊、灌區(qū)建筑物基本信息管理模塊、無損檢測模塊、安全鑒定模塊、鑒定結(jié)果統(tǒng)計(jì)查詢模塊、建筑物基本情況統(tǒng)計(jì)模塊、安全評(píng)估與分析模塊、系統(tǒng)設(shè)置模塊和幫助模塊。 （6）灌區(qū)渠系建筑物安全鑒定軟件系統(tǒng)的應(yīng)用。 以興電灌區(qū)為例，對(duì)其總干渠上的“總干1#公路橋”進(jìn)行安全鑒定計(jì)算。鑒定結(jié)果表明，軟件系統(tǒng)在實(shí)現(xiàn)興電灌區(qū)渠系建筑物安全鑒定計(jì)算功能方面運(yùn)行良好，專家評(píng)價(jià)法、模糊綜合評(píng)價(jià)法以及會(huì)商法用于計(jì)算灌區(qū)渠系建筑物安全等級(jí)的鑒定是可行的。軟件系統(tǒng)界面友好、操作方便、易于維護(hù)，計(jì)算高效準(zhǔn)確，從而實(shí)現(xiàn)了渠系建筑物安全鑒定工作的標(biāo)準(zhǔn)化、程序化，具有良好的應(yīng)用前景和實(shí)用價(jià)值。
[Abstract]:Irrigation is the lifeblood of agriculture is the foundation of the national economy, is the world and national food security. Most irrigation project in China was built in the early days, due to the engineering design and construction of low standard, incomplete supporting, in the natural environment and human factors, changing the material properties of canal system structures and stress state, plus improper management and operation, resulting in engineering ageing disrepair, the occurrence of disease, development, functional decline, canal building irrigation in different degrees have emerged aging disease and damage phenomenon, some engineering facilities can not play its normal function and benefits of the project has been greatly affected, subject to a certain degree of threat to national food safety. The aging disease and damage of irrigation projects and the irrigation area is shrinking, has caused governments at all levels and relevant departments concerned, the state gradually increase the irrigation area Strengthening supporting the transformation of investment and construction, provides a good chance for the governance of irrigation canal system buildings aging disease and damage.
Canal building safety appraisal, is the foundation of the sustainable development of irrigation, is an important part of the reform and renovation of the irrigation district. Strengthening the construction quality and to ensure the effective use of construction funds, improve the level and efficiency of transformation, improve the management level of irrigation area, must be on the canal building aging disease and damage to conduct a comprehensive safety evaluation. Systematic and scientific. The main contents and results are as follows:
(1) modify and improve the safety appraisal index system of the canal system building in irrigation area.
Based on the previous research, according to the different characteristics of various types of canal building, the factors and structure of hydraulic impact as the criterion, consistent feature structure and irrigation canal system buildings follow the principles of the evaluation system, the use of hierarchical decomposition of a complex structure into several parts and components, modification and perfection the safety appraisal index system of canal building.
(2) revising the safety appraisal standard of the canal system building in irrigation area.
According to different canal system buildings, based on the safety identification index system, according to the division standard of the measured values, combined with the specific situation of irrigation area, the safety appraisal standard of irrigation canal system is revised.
(3) establish a mathematical model for the safety appraisal of three kinds of canal system buildings.
By using the principle of expert evaluation method, the experts on the operation condition of building all kinds of canal site assessment, the expert evaluation method to establish model; fuzzy mathematics as a tool, using AHP to calculate the weight of each index, establish the mathematical model of fuzzy comprehensive evaluation, qualitative and quantitative safety appraisal separately for irrigation canal system of the building. Comparing the advantages and disadvantages of the two methods, according to the identification results of the two methods, the law will, the final identification of irrigation canal system buildings.
(4) safety assessment and analysis.
According to the identification results of safety appraisal calculated, statistical analysis results were identified according to the canal system structures of different types of canal building statistical content is divided into 4 levels: function, structure deformation, structure damage, the foundation, the overall security situation that all kinds of irrigation canal buildings.
(5) developing the software system for the safety appraisal of the canal system buildings in the irrigation area.
The WIN XP Chinese platform for the development environment, using Visual Basic6.0 as the front-end development tools, based on the desktop database system Access2003 as the database platform, using ADO technology to access the database, the program design method based on object oriented method is popular nowadays, the development of irrigation canal system building safety identification software system. The software system mainly includes 9 function modules are irrigation irrigation structures the basic information management module, the basic information management module, nondestructive detection module, security identification module, the identification results of the statistical inquiry module, the basic situation of building safety evaluation and statistics module, analysis module, system setting module and help module.
(6) the application of the software system for the safety appraisal of the canal system buildings in the irrigation area.
In Xingdian Irrigation District as an example, the security identification calculation of its main canal on the total dry 1# highway bridge. The identification results show that the calculation function of software system runs well in the implementation of the safety appraisal of Xingdian Irrigation District canal building, expert evaluation method, fuzzy comprehensive evaluation method and commercial law for the identification calculation of irrigation canal system safety grade of buildings is feasible. The software system has friendly interface, convenient operation, easy maintenance, high calculation accuracy, so as to realize the safety appraisal of canal building work standardization, procedures, and has a good application prospect and practical value.
