摘要
土压力计算是基坑工程合理设计的前提,作用在基坑支护结构上的土压力并非是一个恒定值,其大小与基坑围护结构的高度、刚度、位移有关,采用已有的考虑位移的土压力计算方法,分析竖向斜撑体系下围护墙位移与主动土压力的关系,并与规范计算及实测数据进行对比,分析作用在基坑围护墙的土压力变化规律,并说明基坑支护设计时采用考虑位移的土压力计算的必要性。
The calculation of earth pressure is the premise of reasonable design for excavation engineering. The earth pressure acting on the excavation support structure is not a constant value. It is related to the height, stiffness, displacement of the retaining structure. The existing earth pressure calculation method considering displacement is used to analyze the relationship between displacement of retaining wall and active earth pressure on the bracing system. The results are compared with those calculated by the China's code and the measured data. The variation of the earth pressure on the retaining wall is analyzed. The necessity of the earth pressure calculation considering displacement in the excavation engineering design is explained.
