Study on Microstructure Changes of Soft Clay in the Peal River Delt under Dynamic Load

Abstract:

The characteristics and distribution of pores in soil are the key factors in the determination of the physical and mechanical characteristics of soft soil. Using static-dynamic true triaxial test system of modified SPAX-2000 and scanning electron microscope (SEM), the microstructure images of soft clay in the Peal River Delt are studied. By analyzing these microstructure images, eight microstructure parameters including number of pore, total area, classification of area, total perimeter, average diameter, roundness, shape coefficient and anisotropy have been obtained. The changes of microstructure parameters are analyzed ,before and after applying dynamic load . The results show that the change of microstructure parameters has certain rules. This study is help to provide microscopic theory basis for static-dynamic drainage consolidation method to treatment soft ground engineering design.
