不同排距双排抗滑桩的推力分配及受力分析OA

Base on the bank slope support project of Wujiang Double-line Bridge,the thrust distribution and force characteristics of double-row anti-slide piles with different row spacing under complex geological conditions are studied by numerical simulation.The results show that:when the row spacing of anti-slide piles is greater than 17.0 m,the landslide thrust and pre-pile resistance of the front row piles are greater than those of the back row piles,and the distribution of the thrust and resistance is not uniform.The support row spacing is not reasonable.When the pile row spacing is less than 17.0 m,the pile front thrust and pile back resistance of the front row piles and the back row piles are approximately equal,and the two piles are subjected to uniform force,which indicates that it is more reasonable to set double-row piles within the range.When the row spacing between the front row piles and the back row piles is 8.50 m,from the point of view of the force and the pile top displacement,the two piles are reasonably spaced and it is more convenient for the engineering construction,and after the construction is completed within row spacing of 8.50 m,the slope is in a stable state.
