Abstract:

There exist some problems in the traditional anti-slide pile calculation method; especially for the two row piles, this method cannot be used to calculate the distribution of force and thrust on the piles. It is often analyzed by subjective experience so as to cause unreasonable waste. This paper adopts the strength reduction method of finite element to discuss the change of the force before pile, the force after pile and actual force on the two row piles in three different types of landslide with different parameters, along with the change of two row spacing. Some suggestions of two row piles reasonable stress and position are proposed. Due to the different types of conditions are discussed, so the conclusion is universal, and can provide basis for engineering design.

Key words: anti-slide pile, three type landslides, distribution rule
