| 摘 要： | 土压力是作用在挡土结构上的主要荷载，土压力计算是挡土结构设计的重要内容。本文以挖方工程挡土结构土压力计算问题为研究对象，推导了作为判断土压力计算条件重要依据的理论滑动面倾角的计算公式，并针对现行规范中土压力计算条件的判断方法不完全统一的现状，结合工程实例对比分析了不同判断方法及其土压力的计算问题，提出的判断挖方工程挡土结构土压力计算条件的新方法。

| Abstract: | Earth pressure is the main load on retaining structure,and the calculation of earth pressure on retaining structure is an important aspect in structure design.Based on the calculation of earth pressure on retaining structure,the paper deduced the formula of the theoretical inclination of slip plane which is basic to judging standard.Based on practical engineering cases,it analyzed present principles of judging standard and calculation on earth pressure.Meanwhile,being aimed at the present not-unified calculation standard of earth pressure,the paper suggested adopting a unified standard to judge the calculation condition in order to standardize the calculation of earth pressure on retaining structure in excavated volume engineering,which is worthwhile in engineering. |
