The performance assessment of slopes during various disturbances is important to ensure the safe service of slopes. Due to the four characteristics of slope engineering, it is difficult for existing resilience evaluation models to accurately reflect slope performance. To address this problem, a resilience evaluation model applicable to slopes was developed in this study.

The use of a micropile group is an effective method for small and medium-sized slope management. However, there is limited research on the pile-soil interaction mechanism of micropile groups. Based on transparent soil and PIV technology, a test platform for the lateral load testing of slopes was constructed, and eight groups of transparent soil slope model experiments were performed.

Article Synopsis
  • Seismic deterioration effects on anchor cables and slope planes are often overlooked, leading to an overestimation of slope stability during dynamic analysis.
  • This study introduces a new dynamic calculation method that takes these effects into account and proposes a Gaussian mixture model to evaluate slope stability.
  • The findings indicate that considering seismic deterioration yields lower safety factors and more accurate predictions for slope failure probability, aiding in improved seismic design and safety assessments for anchored rocky slopes.

High-performance pumping concrete has been widely used in high-rise building construction because of its superior qualities. However, early cracking problems can occur in cast-in-place pumping concrete, which is due to the excessive use of cement. In this paper, an innovative concrete mixing procedure called "post-filling coarse aggregate concrete" (PFCC) was adopted and applied to large slump concrete.
