Research on the Axial Load Transmission Function of Cast-in-Place Pile in Xigeda Rock Stratum

Abstract:

Load transmission characteristics and rules of pile foundation’s soil-pile system have become one of the basic research contents for pile foundation researchers. Given the different geological and constructive conditions, the load-bearing features of pile foundations in different places have their own rules. Hence, research on the features of load transmission in different places has turned out to be an important project facing all the pile foundation researchers. The Xigeda-rock group is widely spread in Xichang-Panzhihua area in Sichuan Province. This rock stratum is a kind of extremely soft rock, with the nature of argillization, softening, hydrating and cracking with water. According to the static load test data from the pile test in Xinjiu of Panzhihua, this thesis obtained the load-settlement curve with displacement coordinate transformation method. And it is then compared with the actually measured load-settlement curve. Ultimately, the model and value range for parameters of axial load transmission function for cast-in-place pile in Xigeda-rock stratum is proposed.
