Multi-stage embedded pile and frame pile combined structure for reinforcing landslide
By employing a combination of multi-stage buried piles and frame piles in landslides, a reinforcement system with high overall stiffness and strong resistance to deformation is formed. This solves the economic and stability problems of traditional multi-stage single-row anti-slide pile structures in long sliding surfaces and high-thrust landslides, and achieves stability and deformation control under heavy rainfall and strong earthquake conditions.

AI Technical Summary
Technical Problem
传统的多级单排抗滑桩结构在加固长滑面、大推力滑坡时，存在工程造价高、施工周期长、桩体变形大且在强降雨和强震作用下稳定性不足的问题。
Method used
The system employs a multi-stage pile and frame pile combination structure, including single piles, portal piles, and frame piles. Through the combined anti-slide piles, a reinforcement system with high overall rigidity and strong resistance to deformation is formed at the lower part of the slope.
Benefits of technology
It improves the anti-sliding bearing capacity and seismic performance of landslides, reduces material usage, lowers engineering costs, and effectively limits slope deformation. It is particularly suitable for projects with high stability requirements for landslides under conditions of heavy rainfall and strong earthquakes.

Abstract
The utility model discloses a multistage embedded pile and frame pile combined structure for reinforcing a landslide, which comprises at least four rows of slide-resistant piles, the at least four rows of slide-resistant piles comprise at least two rows of single embedded piles, at least two rows of portal type embedded piles and at least two rows of frame type embedded piles which are sequentially arranged along the slope direction of a slope surface from high to low, and the frame type embedded piles are arranged along the slope direction of the slope surface from high to low. The first pile body and the second pile body are sequentially arranged from high to low in the slope direction of the slope surface, and the first beam body is connected with the first pile body and the second pile body. The third pile body and the fourth pile body are sequentially arranged from high to low in the slope direction of the slope surface, and the second beam bodies are connected with the third pile body and the fourth pile body and are arranged at intervals from top to bottom. A combined system formed by the reinforcing structure and the slope body is large in overall rigidity, high in deformation resistance and high in anti-sliding bearing capacity, the safety and stability requirements of a long sliding surface and a high-thrust landslide after reinforcement can be met, and deformation of the slope body can be effectively limited.
