The anti-slide pile is an important method to treat landslide at present. Because of the particularity of rock and soil masses

there are many differences between the practical engineering

landslide thrust of landslide at the back of the pile

soil resistance

failure mode of pile deformation

and theoretical calculation. So we’ve done the physical model test of fortifying landslide with cantilever anti-slide pile

loaded step by step on the top of landslide mass

then obtained some phenomena and lots of test data

the landslide thrust at the back of the pile

soil resistance in the front of the pile and pile strain by using testing equipments. According to the test data

pile failure mode and variation of landslide thrust distribution and soil resistance are analyzed. The test results show that the cantilever anti-slide pile is divided into two parts: separated part and contact part; then landslide thrust has gradually concentrated to the contact part as load increases. Soil resistance in the front of the pile is mainly above 25 cm. It decreases with the depth increasing. The failure model of cantilever anti-slide pile is break-off and the failure point of pile lies 25 cm below the sliding surface. The reason is soil yielding in front of pile caused a large displacement of the pile top and the pile broke off. Finally landslide is instable. These results have reference significant for the actual engineering.
