Abstract

Abstract

In order to provide a reference to seismic design of multi-stage slopes reinforced with anti-slide piles, a sensitivity study on the stability factors of 3D slopes reinforced with anti-slide piles under earthquake action was conducted. Based on the upper bound theorem and combined with pseudo-static method and strength reduction method, the safety factors of slopes were calculated. The sensitivity sequence from strong to weak influencing safety factors of slopes under seismic forces were cohesion, internal friction angles, slope angles, horizontal seismic force coefficients, pile positions, structural parameters of piles, relative ratios of wideth to height for slopes and berm width. Therefore, in the actual construction, the influence of slope angles, seismic forces and anti-slide piles shoud be fully taken into account, and the relative ratios of width to height for slopes and berm width should be rationally laid out according to actual conditions.
