安图大厦软弱下卧层的地基处理

Basement Treatment for Soft Substratum in Antu Building

天然地基土承载力较高,但基础影响深度范围内存在软弱下卧层,不能满足设计要求的承载力和变形时,采用CFG桩法对软弱下卧层进行加固处理。相对于只对软弱下卧层进行加固的方法,CFG桩法不仅提高了软弱土层的承载力,而且提高了整个加固区土的压缩模量;另一方面,CFG桩设计上更可靠,施工工艺更简单,施工质量更容易控制,施工工期更短,经济上更合理。

When natural soil,higher bearing capacity and soft substratum in influence depth,cannot satisfy the request of bearing capacity and deformation,CFG piles are adopted to strengthen soft substratum.Compared with traditional strengthen method to soft substratum,CFG improved bearing capacity of soft substratum and strengthened soil compression modulus.CFG pile is more reliable design,simpler construction technology,more easily control construction quality,shorten construction period and more economically reasonable.
