砂质粉土中沉管灌注桩的质量问题浅析

Elementary Analysis on Several Quality Problems of Sinking Pipe Cast-in-place Pile in Sandy Silt

该文以杭州市七格污水处理厂构筑物的地基处理工程为例,根据该工程不同阶段的沉管灌注桩地基处理的结果,对中等到严重液化的砂质粉土类地质条件下沉管灌注桩施工质量进行分析,并提出了几点相应的预防措施,以供类似工程参考。

Taking the subgrade treatment project of the structures in Hangzhou Qige Wastewater Treatment Plant as an example, and based on the treatment results of the sinking pipe cast-in-place pile in the different stages of the project, the article analyzes the construction quality of the sinking pipe cast-in-place pile under the geological condition of sandy silt being from medium to seriously liquefied, and puts forward several relative measures to the similar projects for reference.
