摘要:

饱和粉细砂地层施工中易产生流沙、管涌等现象,并且有高灵敏度、触变特性,在动力作用下,极易造成土体破坏,所以若施工不当,极易造成沉降过大或塌方现象,主要介绍了杭州市解放路饱和粉细砂层基坑开挖和支护技术。

Abstract:

Sand flowing and piping are prone to occur when construction is performed in ground consisting of saturated fine silt sands. Furthermore, due to the high sensitivity and thixotropy of the ground, ground failure is prone to occur under dynamic actions. In such ground, serious subsidence or collapse will occur if improper construction activities are performed. The article presents the excavation and reinforcement technology adopted for the foundation pit of Jiefang Road Project in Hangzhou, which is situated in saturated fine silt sands.

Key words:  , foundation pit  , excavation  , reinforcement
