摘要:
采用考虑起始水力梯度的非Darcy渗流方程,将Terzaghi饱和黏土一维固结理论推广至可以考虑地面荷载随时间变化的情况,并给出了有限体积法数值计算格式.在此基础上,讨论了起始水力梯度和施工速度对饱和黏土层固结特性的影响.计算结果表明,起始水力梯度越大,地基的固结速度就越慢,且最终固结度小于1;而施工速度的影响主要体现在施工期和竣工初期.
Abstract:
The non-Darcy seepage equation considering the initial hydraulic gradient is used to generalize the one-dimensional consolidation theory of Terzaghi saturated clay to the condition that the ground load can be considered with time, and the numerical calculation format of the finite volume method is given. On this basis, the effects of the initial hydraulic gradient and construction speed on the consolidation characteristics of saturated clay layer are discussed. The calculation results show that the larger the initial hydraulic gradient, the slower the consolidation speed of the foundation, and the final consolidation degree is less than 1. The influence of construction speed is mainly reflected in the construction period and the early stage of completion.
