高渗透砂性土基坑局部二次降水的施工实践

Construction Practice of High Permeable Sandy Soil Foundation of Local Secondary Precipitation

在高渗透砂性土层深基坑施工中,局部深承台二次冲井降水方案较传统全基坑降水方案,保证了工程质量和工期,且大幅度降低了工程降水成本。

The deep foundation pit excavation directly affect the quality, duration, cost, and safety, etc. engineering problems. In particular, for the sandy soil of the precipitation, Hong Care program is too conservative, thus resulting in dramatic increase in the cost of the project. This paper presents new foundation pit construction of an Academic Building in Nanjing HeXi by local secondary precipitation for the first time. Thus reducing the cost of the project precipitation
