建筑基坑侧壁主动土压力计算原则

Principle of Active Earth Pressure Calculation for Side Wall of Foundation Pit

探讨基坑侧壁土压力的研究现状,分析影响基坑土压力的因素,从水土分算、水土合算和适用条件3方面分析建筑基坑结构上土压力计算方法,并通过工程实例对建筑基坑的侧壁主动土压力计算方法进行了论述和分析,得出了考虑渗流作用的水土分算方法更符合实际情况的结论。

This paper discusses the research status of foundation pit side wall earth pressure,analyzes the factors affecting the earth pressure of foundation pit,analyzes the calculation method of earth pressure on building foundation pit structure from three aspects of soil and water calculation separately,soil and water calculation together and applicable conditions.And the calculation method of active earth pressure on side wall of building foundation pit is discussed and analyzed by engineering example,it is found that the calculation method of soil and water calculation separately considering seepage action is more consistent with the actual situation.
