| 英文摘要 | The stability of landslides in reservoir areas is significantly influenced by water level fluctuations and seasonal precipitation events. To mitigate these landslides, a pile-anchor (PA) structure has been developed by adding anchors to common anti-slide piles. However, limited research has been conducted on the behaviours of PA reinforced reservoir landslides under changing environmental conditions. In this study, model tests of PA reinforced landslide were carried out using a multi-field monitoring technique to investigate the behaviours of PA reinforced landslides. The study utilized the Majiagou landslide in the Three Gorges Reservoir region of China as a prototype. Three sets of model tests were conducted to simulate the three different triggers of varying water level, rainfall, and thrust load experienced by landslides in reservoir areas. Furthermore, the performance of PA structures was compared to that of pile structures to demonstrate the superiority of the PA structure reinforced landslide. The results indicated that the behaviours of PA remain consistent regardless of the three different triggers, and their general performance can be divided into three stages: stable, fast-deformed, and slow deformed stage. The distribution of the bending moment exhibits an S-shaped curve, with the maximum bending moment near the slip surface. The maximum negative shear force in the bedrock indicates that part of the structure embedded in the bedrock can effectively resist sliding thrust. In addition, the softening effect can lead to the different responses of PA reinforced landslides under different triggers. This study may provide a deeper understanding of the behaviors of the PA reinforced landslides in response to evolving environmental conditions in reservoir areas. |
