【摘要】：淺圓倉擁有機(jī)械化使用程度高、抗震性能良好等諸多優(yōu)勢,漸漸成為我國近年來大力推廣應(yīng)用的一種倉型。而目前大直徑淺圓倉倉頂傳統(tǒng)施搭設(shè)腳手架施工的方式在一定程度上存在著問題,鑒于此,提出一種新型的大直徑淺圓倉倉頂施工方式,并結(jié)合傳統(tǒng)施工方式以及滑模平臺施工對三種施工方式進(jìn)行科學(xué)評價優(yōu)選,為實(shí)際施工提供指導(dǎo)。本文在研究分析了國內(nèi)外研究現(xiàn)狀的情況下,介紹了目前大直徑淺圓倉主要的結(jié)構(gòu)形式以及各自的特點(diǎn),闡述了已有大直徑淺圓倉倉頂施工方式基本施工工藝及特點(diǎn)并提出新的施工方法;其次,根據(jù)施工方案綜合效益比選的特點(diǎn)將可變模糊優(yōu)選模型與網(wǎng)絡(luò)層次分析法進(jìn)行結(jié)合,并應(yīng)用到大直徑淺圓倉倉頂施工方案優(yōu)選中;在介紹了可變模糊優(yōu)選與層次分析法的根本思想及操作方法后,以施工方案優(yōu)選作為目標(biāo)層,施工便捷性要求、經(jīng)濟(jì)合理性要求、施工質(zhì)量要求、施工安全要求四個因素作為控制層,構(gòu)建可變模糊網(wǎng)絡(luò)優(yōu)選模型,在可變模糊優(yōu)選模型中以施工工期、施工難度、施工成本(人工、材料、機(jī)械使用費(fèi))等11個因素為評價指標(biāo)體系,使用網(wǎng)絡(luò)層次分析法對指標(biāo)進(jìn)行賦權(quán)計(jì)算并將可變模糊優(yōu)選方法應(yīng)用到備選施工方案的優(yōu)選過程中。在案例分析過程中,首先根據(jù)不同施工技術(shù)方案,結(jié)合建設(shè)工程工程量清單綜合單價進(jìn)行人工、材料以及機(jī)械消耗的定量分析,其次,使用Super Decision決策軟件構(gòu)建準(zhǔn)則層的11個評價指標(biāo)的網(wǎng)絡(luò)模型,并計(jì)算其權(quán)重,通過構(gòu)建的可變模糊網(wǎng)絡(luò)模型對大直徑淺圓倉倉頂施工備選滿堂腳手架施工法、滑模平臺兼做施工平臺法、型鋼桁架支撐預(yù)制錐殼板吊裝施工三種方案進(jìn)行優(yōu)選。結(jié)果表明,將可變模糊網(wǎng)絡(luò)層次分析法運(yùn)用到大直徑淺圓倉倉頂施工方案綜合效益比選中是行之有效的,進(jìn)而為大直徑淺圓倉倉頂施工方案決策提供較為全面的決策方法。
[Abstract]:The shallow round warehouse has many advantages such as high mechanization and good seismic performance. It has gradually become a kind of warehouse type which has been popularized and applied in China in recent years. At present, there are some problems in the traditional scaffolding construction of large diameter shallow round silo roof. In view of this, a new type of large diameter shallow round silo roof construction method is put forward. Combined with the traditional construction method and the sliding formwork platform construction, the scientific evaluation of the three construction methods is carried out, which provides guidance for the actual construction. In this paper, the main structural forms and their characteristics of large diameter shallow silo are introduced in this paper, based on the analysis of the current research situation at home and abroad. This paper expounds the basic construction technology and characteristics of the existing construction methods of the large diameter shallow round silo roof and puts forward a new construction method. Secondly, the variable fuzzy optimal selection model is combined with the network analytic hierarchy process according to the characteristics of the comprehensive benefit comparison and selection of the construction scheme. After introducing the basic idea and operation method of variable fuzzy optimal selection and analytic hierarchy process (AHP), the optimal selection of construction scheme as the target layer, the requirement of construction convenience, the requirement of economic rationality, is applied to the optimal selection of large diameter shallow silo roof. Construction quality requirements, construction safety requirements as the control layer, the construction of variable fuzzy network optimal selection model, in the variable fuzzy optimal selection model with construction time, construction difficulty, construction cost (manual, material, material), Eleven factors, such as machine usage fee, are used to evaluate the index system. The weighted index is calculated by the analytic hierarchy process (AHP) and the variable fuzzy optimal selection method is applied to the optimal selection process of the alternative construction scheme. In the process of case analysis, first of all, according to different construction technical schemes, combined with the comprehensive unit price of construction engineering quantity list, quantitative analysis of labor, material and mechanical consumption is carried out, and secondly, Using Super Decision decision software, the network model of 11 evaluation indexes of criterion layer is constructed, and its weight is calculated. Through the construction of variable fuzzy network model, the construction method of full hall scaffolding for the top of large diameter shallow round warehouse is proposed. Sliding formwork platform and construction platform method, steel truss support prefabricated conical shell plate hoisting construction three kinds of optimal selection. The results show that it is effective to apply the variable fuzzy network analytic hierarchy process to the comprehensive benefit ratio selection of the construction scheme of the large diameter shallow round silo roof, and thus provide a more comprehensive decision method for the decision-making of the construction scheme of the large diameter shallow round silo roof.
