| 摘 要： | 以某铁路实际工程利用三排抗滑桩处理大型岩堆为例,基于有限元软件建立等比例实体模型,在初始应力和开挖条件下,采用强度折减法,研究多排抗滑桩在岩堆界面的受力特性,发现了三排抗滑桩在初始应力下的弯矩分配规律,定性分析了开挖阶段三排抗滑桩弯矩分配情况,并对最大水平位移进行了分析。

Study on Mechanical Properties of Three-row Piles by Finite Element Reduction Method |
| |
| Abstract: | Taking a three-row anti-slide pile to treat large rock piles in a railway actual project, an equal-scale solid model is established based on finite element software. Under the initial stress and excavation conditions, the strength reduction method is used to analyze the mechanical characteristics of multi-row anti-slide piles on the interface of rock piles. The bending moment distribution law of three-row anti-slide piles under initial stress was found. The distribution of bending moments of three-row anti-slide piles in the excavation stage was qualitatively analyzed, and the maximum horizontal displacement was studied and analyzed. |
