摘要
首先 ,根据基坑开挖工程的特点 ,推导出考虑位移和时间效应的土压力计算公式 ,以便更好地模拟实际情况。其次 ,在弹性地基梁有限元计算程序的基础上 ,采用考虑位移和时间效应的土压力计算公式对土压力计算程序进行了修改以及对参数反演部分作了相应的修改。最后 ,在实际工程中进行了实用计算和分析。
According to characteristics of foundation pits excavation, the calculation formula of earth pressure which considers effects of both displacement and time has been put forward to meet the requirements of foundation pits excavation.Next,based on the FEM program of elastic foundation beams, the earth pressure calculation program and parameter back\|analysis program have been modified.Some good calculation results have been achieved.Finally,a historic case is studied with the new method of earth pressure calculation.
