【摘要】：中国经济在未来十年会处于高速发展期，建筑业也会随之快速发展。随着建筑业不断发展，高层建筑日益增多，也带来诸多问题。其中，高层建筑施工中安全事故时有发生，给社会造成很大影响。在此背景下，对高层建筑施工的安全评价研究是十分必要的。本文以高层建筑项目为研究对象，围绕高层建筑施工安全评价体系的构建进行研究，做了以下几方面工作： （1）借鉴危险源和安全事故致因理论探寻了高层建筑施工事故成因机理，指出影响高层建筑施工安全的主要因子。通过应用危险源理论，分析出施工主要阶段的危险源；对2010-2012年49例较大高层建筑施工事故案例进行统计，研究事故发生机理；对较大高层建筑施工安全事故进行分类，探寻各事故类型的成因与特征，并分析出影响高层建筑施工安全的主要4个方面。 （2）基于安全事故致因理论，构建了高层建筑施工安全评价指标体系。通过浏览相关文献和咨询专家，遴选适合应用且反映全面的指标，，建立了适合于施工现场各阶段的安全评价的指标体系；利用等差分级方法界定了各指标的取值，为评价指标体系的应用提供了基础。 （3）利用组合赋权和改进TOPSIS原理，建立了高层建筑施工安全评价模型。通过设置固式评价对象，建立四级动态安全评价标准；同时以改进TOPSIS为综合评价方法，既能实现多项目优劣比较，也可以同时输出单项目评价结果，为高层建筑施工安全评价提供了新思路。 （4）应用高层建筑施工安全评价模型，提出施工安全管理建议。通过对华清地产园区内四个高层建筑施工项目分析，应用基于组合权和改进TOPSIS评价模型，结果显示，组合权能够将结果更加离散化输出，改进TOPSIS和传统TOPSIS计算的结果具有一致性，这进一步为模型的应用提供了依据；针对35#施工安全状况相对较差的情况，指出相应的高层建筑施工安全管理措施。
[Abstract]:China's economy will be in a high-speed development period in the next decade, and the construction industry will also develop rapidly. With the continuous development of construction industry, high-rise buildings are increasing day by day, which also brings many problems. Among them, high-rise building construction safety accidents occur from time to time, causing a great impact on the society. Under this background, it is necessary to study the safety evaluation of high-rise building construction. In this paper, the high-rise building project as the research object, around the construction of high-rise building construction safety assessment system to carry on the research, The following works have been done: (1) based on the theory of hazard sources and safety accidents, this paper explores the cause mechanism of high-rise building construction accidents, and points out the main factors affecting the construction safety of high-rise buildings. By applying the theory of hazard sources, the hazard sources in the main stages of construction are analyzed, and 49 cases of construction accidents in large high-rise buildings from 2010 to 2012 are statistically analyzed to study the mechanism of accidents. This paper classifies the safety accidents in the construction of large high-rise buildings, probes into the causes and characteristics of each type of accidents, and analyzes the four main aspects affecting the construction safety of high-rise buildings. (2) based on the theory of safety accident cause, the safety evaluation index system of high-rise building construction is constructed. Through browsing the relevant literature and consulting experts, the index system suitable for each stage of construction site is established by selecting the indicators suitable for application and reflecting all aspects. The value of each index is defined by the method of equal difference classification, which provides a basis for the application of the evaluation index system. (3) the construction safety evaluation model of high-rise building is established by combining weight and improving TOPSIS principle. The four-level dynamic safety evaluation standard is established by setting up the solid evaluation object. At the same time, taking the improved TOPSIS as the comprehensive evaluation method, it can not only compare the advantages and disadvantages of multi-projects, but also output the evaluation results of single project at the same time, which provides a new idea for the construction safety evaluation of high-rise buildings. (4) applying the safety evaluation model of high-rise building construction, put forward the suggestion of construction safety management. Based on the analysis of four high-rise building construction projects in Huaxing Real Estate Park, the results show that the combined weights can make the results more discrete output by applying the combined weight and improved TOPSIS evaluation model. The results of improved TOPSIS and traditional TOPSIS calculations are consistent, which provides a basis for the application of the model. In view of the relatively poor construction safety condition of 35 # construction, the corresponding safety management measures for high-rise building construction are pointed out.
