“…the model test of double-row pile reinforcement (Fan et al, 2019;Xie et al, 2021), the pile-rock interaction process could be divided into three stages: initial deformation stage, rock arch stability stage, and rock arch deformation stage. Ding et al (2020) analyzed the stability of anti-slide piles under the lateral stress of sandy soil. In terms of the stability of anti-slide piles and landslide bodies, it was found that the sliding surface of soft-hard interbedding landslides can be divided into concave type, straight type, and convex type (Li et al, 2017).…”

To study the stability evaluation method and failure mode of reserved rock masses, the Yueyang landslide project was taken as the research object. First, based on the limit equilibrium method and elastic mechanics, the formulas for calculating the stability of a reserved rock mass were analyzed. Second, the failure modes of the reserved rock mass were tested by the experiment model. The results show that the failure modes of the reserved rock mass can be divided into three modes: upward sliding failure, downward sliding failure and tensile crack failure, which are mainly related to the strength and width of the reserved rock mass. Therefore, it is unreasonable to regard a reserved rock mass as a unified failure form in the design of anti-slide pile reinforcement. In addition, although both moderate-strength and strong-strength reserved rock masses exhibit tensile crack failure, moderate-strength rock masses under triangular loading are prone to tension-sliding failure, while strong-strength rock masses under parabolic loading are prone to tension-overturning failure. Finally, the displacement and stress monitoring results in the experiment are basically consistent with the theoretical analysis, indicating that the theoretical analysis results have high reliability.

Green environmental static pressure pile technology has always been one of the problems that many scholars urgently need to study. For the stress test of pile-soil interface, this experiment designed the FBG-MEMS joint test technology between the pile-soil interface during the penetration of static pressure piles in cohesive soil. In this test, a model pile is set up in the model bucket. By studying what effects will happen to the pile-soil interface when the pile is in different positions in the bucket, and studying how the boundary effect affects the changes of the indoor test results, the loading device and monitoring system are used to test the pile pressing force, pile shaft axial force and pile-soil interface stress generated during the penetration of the model pile in the model box. The preliminary test verifies the characteristics of simple operation and high accuracy of the test, and also draws the conclusion that with the increase of the penetration depth, the axial force of the pile shaft and the effective lateral pressure of the pile-soil interface increase, but the lateral pressure at the same depth gradually decreases. In addition, the influence of boundary effect is further analyzed. Finally, it is concluded that the boundary effect will increase the pile driving force, pile shaft axial force and effective side friction. The research results have important reference significance for green environmental protection static pressure pile technology in practical engineering.

A closed‐form formulation for the dynamic analysis of lateral response of floating piles in a saturated finite‐thickness soil layer is presented in this paper. Governing equations of the saturated soil are established on the basis of Biot's poroelastic theory, solution to which results in the lateral resistance of surrounding saturated soil to pile deflection. Closed‐form expressions of the lateral deformations of pile along depth and the dynamic compliances at pile head are obtained by solving a system of linear equations from the boundary and continuity conditions, instead of solving sophisticated integral equations in existing boundary integral methods. The parametric study focuses on exploring the sensitivity of pile compliances and deformations to the main problem parameters, including pile‐soil modulus ratio and soil permeability.
