某工程防渗区域地面地基处理方案比较

Comparison of Foundation Treatment Schemes in Anti-seepage Area of a Project

当前防渗处理的主要方式是铺设防渗膜,而防渗膜对地基的沉降要求比较严格,不允许出现较大的差异沉降。在软弱地基防渗区域,采用的地基处理方案既要满足地面荷载要求,又要满足防渗对地基差异沉降的要求。以实际工程展开比较,对比了多种软弱地基防渗区域地面地基处理方案,以期为工程的设计提供技术依据和参考。

At present,the main method of the anti-seepage treatment is to pave anti-seepage membrane,but the anti-seepage membrane has strict requirements on the settlement of the foundation,and large differential settlement is not allowed.The foundation treatment schemes adopted should not only meet the requirement of ground load,but also satisfy the requirement of anti-seepage for differential settlement of foundation in the soft foundation anti-seepage area.The paper makes a comparison of foundation treatment schemes in several soft foundation anti-seepage areas in the hope of providing technical basis and reference for engineering design.
