深厚软弱粘性土沉降处理技术

Sedimentation technology for clay soil

包钢自备电厂 1#、2 #冷却塔零米标高与自然地面标高平均相差 4.38mm ,地基土力学性能差 ,大型塔基对压缩层影响达 35 0m ,地基压缩变形不能满足设计要求。利用回填土辅以动态观测技术 ,即解决场平问题 ,又解决基土沉降过大问题 。

Zero-mark in design of 1# and 2# Cooling Tower contrasts 4.38mm with ground mark. Because mechanical property of foot soil is not good, large tower foot on compression is 35m. Design of foot compression deformation can't meet this requirement. Using backfill and active research can solve these problems, which is adopted firstly in North.
