Qian, Y.; Li, M.; Jin, Y., and Wang, R., 2019. Undisturbed soil test on the effects of the slope angle of plate for anti-overturning resistance of rigid CEP pile used for oceanographic engineering. In: Li, L.; Wan, X., and Huang, X. (eds.), Recent Developments in Practices and Research on Coastal Regions: Transportation, Environment and Economy. Journal of Coastal Research, Special Issue No. 98, pp. 46–49. Coconut Creek (Florida), ISSN 0749-0208.The rigid concrete CEP pile has an important foundation in oceanographic engineering because of its higher anti-overturning resistance. This paper, through the undisturbed soil test, studies the effects of the slope angle of plate on the failure state of the soil surrounding the rigid CEP pile under horizontal force and designs different expanded plate slope angle models in the case of undisturbed soil. By preparing the pile-soil model and conducting the loading test, the test analyses the effects on the bearing capacity of the rigid CEP pile and the failure state of the soil and compares them with the results obtained by the ANSYS analysis model. Conducting the test on undisturbed soil is an improvement and innovation to the current buried soil-model testing method and test equipment. It achieves vertical and horizontal loading simultaneously and ensures the reliability of test results. This paper benefits the study of the CEP pile and large-scale application of it in future oceanographic engineering.
