摘要
针对实际工程中基底反力的分布特点和基础沉降特征,用有限元方法,计算分析得出:当地基加固后,筏板下地基呈现中心刚度大,而边缘刚度小时,可以有效减小差异沉降,继而减小由于沉降差异而引起的基础次应力。以便为工程设计中寻求经济合理的地基处理方案提供参考。
According to the feature of base reaction and base settlement, the influence of soil treatment to maximum settlement and differential settlement of foundation as well as internal force of foundation have been computed and analyzed with the finite element method. So that this can support reference for the soll treatment project in practice, which try. to seek economical and reasonable scheme.
