The Optimization Research on Treatment of the Soft Clay Foundation

Abstract:

The article is about the treatment of deep soft clay foundation of the highway project in Yunnan province. Firstly, it analyses the principle and the different features of vertical enhance body composite foundation, including gravel pile, cement soil pile, CFG pile. All kinds of condition should be considered, such as soft clay characteristics, clay mechanics index, the bearing capacity calculation, settlement and stability analysis, to get a treatment plan by using the results of qualitative analysis and quantitative calculation. Then it verifies treatment effect and summarizes characteristics and treatment laws of deep soft clay depending on the detection and construction monitor to guide design and construction.
