Abstract

Abstract

The evolution mechanism of landslide anti-slide pile system is an important theoretical basis for landslide hazard prevention. Pile-soil interaction is the key of landslide anti-slide pile system, and displacement field is one of the important symbols of interaction. Therefore, the study of displacement field of landslide anti-slide pile system is of great significance in the field of engineering. Based on the engineering geological characteristics of accumulation landslide in Three Gorges Reservoir area, a large-scale physical test model is established. The thrust of the rear edge of the landslide is simulated by applying load step by step. The displacement data of the landslide slope surface and the top of the piles are obtained by using high-speed video camera and particle image velocity technology, and the variation characteristics of the displacement field of the system are quantitatively analyzed. The test results show that the displacement field presents a good regularity in the evolution process, which plays a certain role in promoting the research on the mechanism of pile-soil interaction.
