基坑工程中围护结构入土深度,一般是由坑底抗隆起稳定性决定,现行规范规定推荐的圆弧滑动法的验算方法只是针对一般情况,特别是柔性围护结构。考虑逆作法施工的特点及其他一些有利因素的影响,提出修正的圆弧滑动法以适合刚性围护结构的抗隆起验算。并通过一个工程实例的设计验算,对逆作工况下地下连续墙入土深度进行一定的探讨和优化。
In excavation engineering
the depth of retaining wall is generally determined by the analysis of anti-heaving stability. The checking formulas of current codes
arc-slippage method
is suited to general conditions
especially in the condition of flexible retaining wall. Considering the characteristics of top-down construction and other advantage factors
a so-called modified arc-slippage method is proposed for rigid retaining wall. And with the analysis of engineering instance
the depth of diaphragm wall in top-down construction could be optimized.
