Research on Reinforcement Effect on Landslide with Triangle Anti-slide Piles
摘要
Abstract
By using the FLAC3d program, the reinforcement effect on landslide with triangle anti-slide piles which designed by the unit of group is researched.The triangle anti-slide piles can be divided into two forms by whether having the tie beams.By simulate calculation, in arrangement for triangle anti-slide piles on the slope, FOS of slope, side displacement of piles, bending moment and shear stress of piles are compared and analyzed. Results show that the FOS of slope increase obviously when there are beams between the piles;side displacement of each pile in a group is basically the same;The bending moment of pile top increases obviously, the distribution of the bending moments is relatively uniform above the sliding surface, and those below decrease relatively;the shear stress of each pile tip has increased, above the sliding surface the shear stress peak of the front row has decreased, the back row has increase, and the amplitude of each pile is uniform.Then compared with the common double rows, it can seen that, when layout the triangle anti-slide piles, the FOS of slope is bigger, the displacement is small, and they can save material to prove its superiority.Above all, the triangle anti-slide piles which have beams on its top is a structure form more worthy in the anti-slide piles design.关键词
