基于WSR和熵权物元可拓理论的深基坑安全风险评价

Safety risk assessment of deep foundation pit based on WSR and entropy weight matter element extension theory

为客观合理地对深基坑安全风险进行评价,引入WSR方法论,以物理-事理-人理为基础,从3个维度分析深基坑施工安全风险,构建以人理为核心的深基坑施工安全风险管理评价指标体系。并运用熵权法和可拓学理论构建深基坑安全风险评价的熵权物元可拓模型,利用该模型对某建设项目深基坑安全风险等级进行评价,最后通过评价结果的分析从物理、事理、人理3个维度提出相应的改进措施。

In order to evaluate the safety risk of deep foundation pit objectively and reasonably,WSR methodology was introduced.The safety risk of deep foundation pit was analyzed from three dimensions of physics(W)-theory(S)-humanism(R),and the management assessment index system was constructed with humanism at the core.The entropy weight matter-element extension model of deep foundation pit safety risk evaluation was constructed by using entropy weight method and extension theory.The model was used to evaluate the safety risk level of a construction project.Finally,the corresponding improvement measures were put forward from the three dimensions of physics(W)-theory(S)-humanism(R)through the analysis of the evaluation results.
