| Anti-slide pile have a lot of advantages, such as anti-sliding ability, widely applicable condition, the state of landslide, worsening of construction, and more convenient to verify such outstanding advantages, so which is widely used in the engineering field. Scholars both at home and abroad have finished a lot of studies about it, but still have many shortcomings. The design for double row pile, the traditional calculation method is simplified pile and soil for planar problem, does not take into consideration of pile body section for landslide thrust. Based on double row pile thrusting force studies, and summarizes the front row pile, the composition, thrusting force piles combined formula, can be used in engineering practice presents the thrusting force calculation method of pile. The main research contents and acquired results follows:(1)Using ABAQUS to calculate the transfer process of landslide residual thrust, and comparing with traditional transfer coefficient method, proved transfer coefficient method in calculating the thrusting force on the accuracy could satisfy the requirements engineering practice.(2)By changing the distance between the former, and the rear pile, and analyzing the rule of landslide thrust between the former and the rear pile. Have drawn a conclusion that the thrust of the landslide in former pile is made up of thrust passed by the rear row pile, thrust passed by soil in the rear row pile side and thrust between piles of the rear piles.(3) By analyzing the landslide thrusts in different pile, reached the scope of influence in piles, and combined "K" method with transfer coefficient method, reached the formula of the former pile and the rear pile. By compare the results of calculated and the results of numerical simulation, The calculated results are right, and raised a method of double row pile which is suitable for actual application.(4) By using the method of engineering examples to the inspect the feasibility in front ways.
