摘要
借鉴载荷试验法确定地基承载力的思路:沉降s急骤增大,荷载-沉降(p-s)曲线出现拐点为极限承载力值。再根据安全系数和挡墙极限高度与地基承载力的关系,分析了挡墙极限高度与挡墙厚度、地基土强度和地下水位的关系。为探索挡土墙能够建多高这个问题提供了一个新思路。
This paper draws on the experience of confirming the bearing capacty of the foundation soil through the load test and is on the basis of the relationships between the bearing capacty of the foundation soil and the safety factors and the limiting height of the retaining wall.This paper analyzes the relationships between the limiting height of the retaining wall and the thickness of the retaining wall,the strength of the foundation and underground water level,hoping to provide a new way to explorie the limiting height of the retaining wall.
