Application of Cement Dry Jet Mixing Pile in River Bed Foundation Treatment

GUO Li;Fushun City Water Conservancy Survey Design Institute;  
In the paper,single pile settlement calculation Q-s figure and single pile composite foundation settlement p-s figure in Dengta irrigation area and Dahuofang reservoir are obtained according to primary consolidation settlement theory of cement dry jet mixing pile composite foundation. Single pile vertical compressive static load test and single pile composite foundation static load test indicate that cement dry jet mixing pile treatment foundation has excellent effect in Dengta irrigation area and test results and settlement calculation are deviated due to geological complexity in Dahuofang Reservoir.Different geological conditions have decisive influence on pile foundation. It is expected that the paper can provide reference for related study.
