Study on the Impact of Bridge Pile Excavation on the Stability of Deep Loose Deposits Slope
This paper takes the deep deposit slope of Longwangxi as a case study. Using the method of strength reduction, the stability of pre-disturbance and post-disturbance conditions is calculated separately to investigate the influence of human-induced disturbances during bridge pile construction on slope stability. The research results indicate that excavation operations lead to a decrease in the safety factor of slope stability by 7.1% to 11.7%. It is recommended to provide slope support before bridge pile construction. Plastic zones and areas with significant displacements are mainly observed in the upper and lower portions of steep slopes, while the middle section with gentler slopes remains in a stable state. It is advisable to implement slope support measures separately for the upper and lower parts of the slope. Additionally, human-induced disturbances may result in significant displacement zones in the root zone of isolated boulders above the slope, leading to instability. Therefore, it is suggested to focus on stabilizing the root soil of isolated boulders when addressing their instability and to implement targeted measures before commencing bridge pile construction.
