【摘要】：由于規(guī)劃設(shè)計(jì)、施工質(zhì)量、自然老化和運(yùn)行管理等方面的原因，我國早期修建的渡槽，很多已經(jīng)進(jìn)入了病險(xiǎn)期，出現(xiàn)了不同程度的老化病害問題，，渡槽健康狀態(tài)隨時(shí)間逐年下降，既存在安全隱患，又不利于延長渡槽使用壽命和發(fā)揮渡槽的工程效益。因此，應(yīng)用科學(xué)合理的評(píng)價(jià)方法對(duì)渡槽健康狀態(tài)進(jìn)行客觀而準(zhǔn)確的評(píng)價(jià)，并在此基礎(chǔ)上針對(duì)不同健康狀態(tài)的渡槽進(jìn)行科學(xué)合理的維護(hù)、管理和改造，已成為當(dāng)前和今后一段時(shí)間內(nèi)渡槽建設(shè)和管理中一項(xiàng)亟待解決的問題。 本文討論了渡槽健康狀態(tài)評(píng)價(jià)的研究現(xiàn)狀和與渡槽結(jié)構(gòu)類似的橋梁健康狀態(tài)評(píng)價(jià)方法，提出在借鑒橋梁結(jié)構(gòu)評(píng)價(jià)研究成果的基礎(chǔ)上，結(jié)合渡槽結(jié)構(gòu)自身的特點(diǎn)，采用基于AHP-熵權(quán)法的模糊綜合評(píng)價(jià)方法對(duì)渡槽健康狀態(tài)進(jìn)行評(píng)價(jià)。本文主要開展了以下幾個(gè)方面的工作： 首先，從研究影響渡槽“健康”的老化病害問題著手，對(duì)渡槽老化病害主要表現(xiàn)形式進(jìn)行了歸納總結(jié)，并系統(tǒng)地分析了渡槽老化病害的形成原因。 其次，論述了AHP-熵權(quán)法和模糊綜合評(píng)價(jià)的基本原理以及在渡槽健康狀態(tài)評(píng)價(jià)中的應(yīng)用，為渡槽健康狀態(tài)評(píng)價(jià)體系的建立打下了一定的基礎(chǔ)。 第三，應(yīng)用前面論述的理論和方法，以梁式渡槽評(píng)價(jià)為例進(jìn)行研究，將渡槽健康狀態(tài)評(píng)價(jià)等級(jí)劃分為五類，建立了渡槽健康狀態(tài)綜合評(píng)價(jià)模型，并采用AHP-熵權(quán)法計(jì)算了各層指標(biāo)的權(quán)重。然后結(jié)合現(xiàn)有資料及相關(guān)規(guī)范，確定了渡槽部件等級(jí)參考評(píng)定標(biāo)準(zhǔn)，提出了確定底層評(píng)價(jià)指標(biāo)隸屬度的方法。在此基礎(chǔ)上，論述了渡槽健康狀態(tài)多級(jí)模糊綜合評(píng)價(jià)的具體過程。 最后，以湖南省內(nèi)某渡槽為工程實(shí)例，采用本文提出的基于AHP-熵權(quán)法的模糊綜合評(píng)價(jià)方法，對(duì)其健康狀態(tài)進(jìn)行綜合評(píng)價(jià)，結(jié)果表明該綜合評(píng)價(jià)方法是合理的、可行的。
[Abstract]:Due to the reasons of planning and design, construction quality, natural aging and operation management, in the early construction of the aqueduct in our country, many have entered the disease risk period, and the problem of aging disease of different degrees has occurred, and the health status of the aqueduct decreases year by year, which is not only a potential safety hazard, And the service life of the aqueduct is prolonged and the engineering benefit of the aqueduct is realized. Therefore, the scientific and reasonable evaluation method is applied to the objective and accurate evaluation of the health status of the aqueduct, and the scientific and reasonable maintenance, management and transformation of the aqueduct with different health conditions are carried out on the basis of the evaluation method, It has become an urgent problem to be solved in the construction and management of the aqueduct in the current and future period. In this paper, the research status of the evaluation of the health status of the aqueduct and the method of evaluating the health status of the bridge similar to the aqueduct structure are discussed. A fuzzy comprehensive evaluation method based on AHP-entropy method is used to evaluate the health status of aqueduct The price is mainly carried out in the following aspects: First, from the study of the problem of aging of the "health" of the aqueduct, the main manifestations of the aging disease of the aqueduct are summarized, and the shape of the aging disease of the aqueduct is analyzed systematically. In this paper, the basic principle of the AHP-entropy and the fuzzy comprehensive evaluation and the application of the evaluation of the health status of the aqueduct are discussed, and the establishment of the evaluation system for the health status of the aqueduct is laid. Based on the theory and method discussed above, the evaluation of the health status of the aqueduct is divided into five categories, and the comprehensive evaluation model of the health status of the aqueduct is established, and the AHP-entropy method is used to calculate the health status of the aqueduct. The weight of the index of each layer is determined. Then, based on the existing data and related specifications, the grade reference evaluation standard of the aqueduct component is determined, and the evaluation of the bottom layer is put forward. On the basis of this, the multi-level fuzzy synthesis of the health status of the aqueduct is discussed. In the end, a fuzzy comprehensive evaluation method based on the AHP-entropy method, which is based on the AHP-entropy method, is adopted to evaluate the health status of an aqueduct in Hunan Province. The results show that the comprehensive evaluation method
