摘要
假定土体横向受载时为弹塑性的本构关系,对墙体与土体进行共同作用分析,发现在墙体变形过程中,墙体两侧土压力是动态变化的,背侧土压力接近主动土压力,开挖侧土压力在浅层范围内接近于被动土压力,往深层向静止土压力过渡。
In this paper ,a new method is discussed for calculating retaining wall displacement. The soil stress-strain relation is supposed to be ideal elastic-plastic. By the analysis of soil-wall reaction. It reaches a conclusion that soil pressure is always variable. Generally speaking tSoil pressure on the back of wall is almost egual to active soil pressure while Soil pressure on the side of excavation is less than passive soil pressure in shallow depth,approaching to static soil pressure with increment of depth.
