| 摘 要： | 通过对深基坑在开挖过程中变形受力特性的力学机理研究，结合基坑施工中各参数指标间的力学相关性及其统计关系，定量确定多参数之间协调关系和所对应的风险情况，提出融合多参数的风险评估预警方法并编制多参数风险评估程序.该方法相对常规单参数风险预警控制方法，更能反映基坑支护结构及周围环境的内力变形情况.采用该方法对上海某地铁车站基坑工程进行多参数风险评估.结果表明,该方法能够判定出单参数方法所不能识别的基坑风险，有效弥补单参数控制的不足和漏洞，具有很好的实用价值.

| Abstract: | A new risk evaluation method of deep excavation was presented by considering the correlation of multiple parameters. The load transfer and deformation of retaining structure and surrounding soil were analyzed to discuss the correlation mechanism of different parameters during deep excavation. The quantitative relationship among these parameters was determined by the statistical analysis. A multi-parameter risk evaluation method and software were then proposed based on the correlation analysis of multiple parameters. The presented method was applied in a case of metro station in Shanghai. The results show that some risk during construction which can not be warned by the traditional methods is found in the new method.
