本文主要对横陡坡条件下桩墙联合支挡结构体系中抗滑桩的受力特性进行深入研究。首先按照FLAC3D的建模分析方法,得到完整的路基边坡工程数值分析模型,并进行了施工过程的数值模拟;然后通过提取并整理相关的数值模拟数据,对抗滑桩的受力状态、位移变化等情况作了详细的数值模拟结果分析。结果表明这种桩墙联合支挡结构能发挥稳定的抗滑作用,抗滑桩在中部受力较大而在桩顶和桩底受力较小,且抗滑桩自由段的水平位移要远大于嵌固段。
In this paper, the stress characteristics of anti-slide piles in the composite wall-supported system under lateral steep slopes are studied in detail. Firstly, according to the FLAC3D modeling and analysis method, a complete numerical analysis model of subgrade slope engineering is obtained and the numerical simulation of the construction process is carried out. Then by extracting and sorting the related numerical simulation data, the stress state and displacement change of anti- Etc. made a detailed numerical analysis of the results. The results show that the joint support structure of the pile wall can exert a stable anti-slip effect. The anti-slide pile is stressed in the middle and less stressed on the top and bottom of the pile, and the horizontal displacement of the free section of anti- In the embedded section.
