河北省邯郸矿区千吨冷库工程,原由邯郸设计研究院设计,主库采用了独立墩式基础承重,围护墙是毛料石基。开工后,首先开挖成40m×50m、深2m的大坑,拟在局部开挖做独立基础。该工程地质条件,表层是近3.3m厚的粉细砂层,其下是胶结砂砾石层(持力层),见图1。因该工程地下水陡升,原已?
Handan Mining District, Hebei Province tons of cold storage project, originally designed by Handan Design and Research Institute, the main library with independent pier-type foundation load-bearing, retaining wall is wool stone base. After the start of the excavation, a large pit of 40m × 50m and a depth of 2m shall be excavated first. It is proposed to be an independent foundation for local excavation. The project geological conditions, the surface is nearly 3.3m thick fine sand layer, which is cemented gravel layer (holding layer), shown in Figure 1. Due to the steep rise of the project groundwater, originally?
