Abstract: On the basis of the gade settlement and pore water pressure detected in the plate loading test and static load test in situ, the reinforcement effect of composite ground with crushed rock file is analyzed. After being treated with crushed-rock piles, the settlement of compound ground reduced effectively, the dissipation of pore water pressure accelerated, and the effective stress of the soil body increased continuously. the deformation of the ground is vertical mainly and the soil is consolidated.
Keywords: crushed rock pile; settlement; pore water pressure; detection
