摘要

摘要: 从风险理念上出发,通过对基坑事故的广泛调查,得到深基坑安全性的主要影响因素及其所占权重,据此结果对深基坑安全风险等级进行评判。首先,简要地介绍了深基坑工程发展现状、工程中可能存在的各种风险、目前基坑工程等级划分情况等;其次,总结由大量深基坑事故调查所得到的各种原因,并统计分析,从而得到深基坑安全风险的各种影响因素和对应的权重;最后,介绍了模糊综合评判法,它具有很强的实用性,可以广泛地用于各工程中。构造了基坑风险评判矩阵,对深基坑安全等级进行二级评判,运用模糊综合评判法定量计算了基坑的风险等级,并结合上海港国际客运中心深基坑工程,用模糊综合评判法进行了实例分析,所得结果符合工程实际情况,有利于提高深基坑整体安全水平,为工程提供了一些参考价值。

Abstract: Based on the risk idea and the safe factors of excavations as well as the weights obtained from the investigations of excavation accidents, the safe grade of excavations is analyzed. First, the development situation, possible risks in the project and the current grade division in excavations are briefly introduced. Then all kinds of reasons obtained from a large number of excavation accidents are statistically analyzed. Each influence factor in excavation safety and its weight are obtained. The fuzzy synthetic evaluation method is introduced, which can be used largely in many projects. At the same time, the judgment matrix is constructed and two levels of judgment for the excavation safety are carried out. Quantitative calculations are made by using the fuzzy synthetic evaluation method. Finally, the excavation project of Shanghai International Passenger Transport Centre is analyzed. The results conform to the actual situations of the project. Thus the fuzzy synthetic evaluation method is favorable for raising the overall safety level of the excavation, and it can provide some reference values for projects.
