基坑支护中水土压力合算与分算的综合分析

The Comprehensive Analysis of Water and Earth Pressures Together and Separately on Supporting Pit

分析了水土分算和水土合算的计算方法,并给出了在不同情况下水土分算的合理计算公式.提出了当采用不固结不排水强度指标时的土压力计算方法.通过将这些算法与实际工程的比较发现了“广义”水土合算法的不安全性,并找出了几种合理的算法.

The paper analyses the calculating ways of estimating water and earth pressures separately and estimating water and earth together, gives out several reasonable formulae of estimating water and earth pressures separately and puts forward the way calculating earth pressures with the strength parameters of UU. Through comparing the results from calculation with results from practical engineering, the paper points out the unsafety of the general water and earth together and builds several reasonable formulae.
