| 摘 要： | 利用Laplace变换的方法,给出了在任意多级加载作用下,并综合考虑了竖井地基的井阻和涂抹作用下频域内固结解。通过Laplace逆变换,结合具体算例对影响竖井地基固结的主要影响因素进行了详细分析,并与已有结果进行了比较。结果表明,利用本文方法对任意多级加载的情况可以方便求解,而且计算过程简单,计算速度快,精度高。

| Abstract: | The general solution in the Laplace transform field for the consolidation of soil with vertical drains considering well resistance and the smear action under multi-ramp time-dependent loadings was derived.Then by the Laplace inversion the average degree of consolidation of the vertical drain under multi-ramp time-dependent loadings could be calculated.According to numerical examples,the influences of parameters of vertical drains were investigated;and it seems that the method of this paper is particularly efficient and convenient for solving engineering practice |
