基坑中软土的水平抗力系数几种确定方法探讨OA

This paper discusses the determination method of the horizontal resistance coefficient of soft soil in foundation pits.It analyzes the source of the proportion coefficient m in the horizontal reaction coefficient of soil in the foundation pit regulations,and analyzes the theory of determining the horizontal resistance coefficient.It lists the empirical values of the horizontal resistance coefficient of soft soil in current specifications.Finally,through case analysis,the calculation results of the horizontal resistance coefficient of the three types of soil(m value,k value,and c value)are compared with the actual measurements.It is found that the proportion coefficient m value of the horizontal reaction coefficient of soft soil calculated according to the current foundation pit regulations formula is relatively small.
