排水箱涵地基失稳的加固处理

Consolidation Treatment of Ground Foundation Stability Loss of Drainage Box Culvert

汕头市地理位置濒临海洋 ,属海滨城市 ,地质情况差制约着城市构筑物建设进度。汕头市南滨路某排水箱涵工程 ,位于厚度二十多米的海滩淤泥层上 ,地理位置、地质情况较为特殊。本文简要介绍该箱涵地基高压旋喷桩加固处理的过程 ,并以此为实例 ,提出工程构筑物软基处理的方法 ,避免原土地基前期由于地质情况差。地基沉降不均匀而造成构筑物出现破坏 ,使构筑物满足不了其使用功能 ,降低了构筑物的使用标准。

Shantou City faces to sea, it belongs to seaside city. The poor geological conditions restrict the construction progress of the urban structures. A drainage box culvert project of Nanbin Road in Shantou City is located silt course of sea beach with more than 20m in thickness. The geographical position and geological condition are more special. The paper imroduces briefly the course of consolidation treatment of high pressure chemical churning piles of the ground foundation of the box culvert. And it puts forward the method of soft soil foundation treatment of the engineering structures, taking it as the example so as to avoid the structures' destruction by the poor geological conditions and thc uneven ground settlement in the earlier stage of the original soil foundation. So the structures can not meet the use function and reduce the use standards of the structures.
