“…Li et al [9] proposed an improved method for calculating the seismic displacement of a slope supported by soil nails under an earthquake. Some researchers [10,11] analyzed the safety of soil nailing support structures under seismic loads. Some scholars also investigated the dynamic response of structures for different support configurations and assessed the influence of the amplitude of acceleration above 0.4 g on the soil nailing support using model tests [12,13].…”

The ground vibration induced by pile driving affects the safety of the adjacent foundation pit. In this paper, the influence of pile-driving vibration on the soil strength and the nail-soil interface strength was studied, and the variation in the axial force and displacement of the soil nail under vibration was analyzed. The paper studied the effects under different vibration parameters on the soil strength and the nail-soil interface strength by using a vibration exciter and a nail pull-out model box. The results showed that the stronger the excitation force was and the higher the frequency was, the greater the attenuation of the soil strength and nail-soil interface strength was. On the contrary, the change of the internal friction angle of the soil was not obvious under the vibration. The nail-soil interface strength recovered when the vibration terminated. Decreases in c and τp led to an increase in the working length of the soil nail, a redistribution of the axial force, and an augmentation in the soil nail displacement.

By adopting a hinged form at the bearing joints of the traditional framework anchoring systems, a new overall flexible slope supporting system—hinged framework anchoring system was established. The system can not only keep anchoring force transmission mechanism to ensure the overall slope reinforcing effect, but also allow the slope to have finite deformation to dissipate energy (under dynamic mechanism). A flexible hinged frame anchored theoretical model is established and solved based on finite difference program FLAC3D. Strength reduction technique is used to evaluate the slope stability and obtain the factor of safety. By the comparative analysis of rigid frame connected supporting system, internal force and deformation of each component part of different supporting system are compared. The results showed that: the flexible framework anchoring system can effectively control the slope sliding to ensure the slope stability. At the same time, the flexible supporting system had obvious advantages of improving its stress states compared to the traditional framework anchoring system. With a new framework for anchoring flexible hinge supporting system was proposed and analyzed, a new design idea in slope reinforcement is provided, while a basis for the application of the new supporting system is provided.

“…The reinforcement on slope has become an important measure to guarantee the safety of infrastructure, such as hydropower, construction, road, bridge and other engineering structures. However, the common analysis method of slope safety factor is rigid body limit equilibrium method, which uses slice method to make a hypothesis for normal stress and tangential stress on slide surface, ignoring the coordination between stress and deformation [1,2]. Different results will be caused by different hypothesis, which usually lead to some deviations in prediction of slope stability, especially to anchored slope.…”

The stability of slope is closely related to stress-state. Assumptions about stress-state in the rigid body limit equilibrium method are not satisfied with the demands of deformation compatibility principle. So the stability analysis method compatible with slope stress and anchorage system should be established for anchored slope. The pseudo cohesion concept theory is used to analyze the improvement of stress-state due to anchoring measures, and the stability safety factor of anchored slope by sliding surfaces searching method is obtained, in which grid control is used and embedded in FLAC3D. The result shows that the safety factor with the pseudo cohesion theory is 1.43 while the strength reduction method is 1.41. The similar results for them show the validity of proposed method. What's more, the suggested method has an advantage of short time consuming.
