Researches on lateral support behavior of large diameter rock-socketed cast-in-place piles at river port by laboratory model test

To investigate large diameter rock-socketed cast-in-place piles and the behaviour of rock under lateral load,large model tests were conducted.Considering the prototype characteristics of rock and piles,the scale of model was selected as 1:20.The mixture ratio of sand: gypsum: water by weight was 5.6:0.8:1 to simulate bedrock,and the organic glass was used to simulate concrete piles.The mechanical behaviour of piles and bedrock was studied under different horizontal loads.The test results would be helpful to the large diameter rock-socketed cast-in-place piles in the soft bedrock under lateral loads.
