摘要: 找到了圆形刚性承压板作用下均匀地基位移的一般表达式和两层、三层水平成层地基的位移表达式。以此为基础,利用直接法进行分层弹模计算,并编制了相应的计算软件。采用的改进约束变尺度方法稳定快速,优化了分层弹模计算。

Abstract: The general expressions of displacement for uniform and three-layers horizontally stratified foundations are found. On the basis of above mentioned formulas, the calculation on elastic moduli of stratified foundation is made with direct method and a corresponding calculation software programmed. By use of an improved variable metric method the calculation of elastic moduli is optimized.
