摘要
根据土压力与位移关系的一般特征,将基坑支护结构上的土压力与位移的关系用双曲线来表示,推导了考虑位移变化影响的土压力计算公式.该公式描述了土压力随位移变化的非线性特征,公式中控制参数可以结合室内试验方便地得到.
According to the general characteristics of the relationship between the earth pressure and displacement of soil, the relationship between the earth pressure on the support structure of foundation pits and displacement is expressed by a hyperbola, and a formula is derived for calculation of the earth pressure, in which the variation of soil displacement is considered. The formula can reflect the nonlinear characteristics of the relationship, and the governing parameters of the formula can be obtained through laboratory tests.
