INSTALLATION OF H-SHAPED AND TEST OF ITS EFFECTIVENESS AT A POWER PLANT IN SHENZHEN

Pile - foundation is one of the safe and reliable measures for main buildings and constructions of large - scale engineering project in the area , where the upper part consists of failling granite fragments, the lower part consist of soft clay, and groundwater and seawater are connected with each other.
