摘要

考虑井阻作用，推导了等应变条件下竖墙地基水平向固结解析解，并与等应变条件下的竖井地基径向固结解析解进行比较，得到竖墙地基平面应变问题和竖井地基轴对称问题之间的等效方法。该方法转换公式简单，且能保证两种情形下同一深度处平均孔压在任一时刻相等，确保了转换为平面应变有限元分析的准确性。

Abstract

Solution for the horizontal consolidation of vertical wall with resistance under the condition of equal vertical strain is presented.It is compared with the solution for the radial consolidation of vertical drain wells under the same condition. An equivalent calculation method to convert axisymmetric vertical drains foundation into plane strain vertical wall foundation is put forward.This method uses a simple formula when doing the conversion

and it can maintain the same average degree of consolidation of arbitrary depth at each time step

consequently it can ensure the veracity of the conversion.
