摘　　要：册亨县某储能项目根据规划设计图平场后形成了高10 m的不稳定土质边坡。为不影响坡脚规划道路的正常使用,需对其进行支护设计。根据土压力计算结果,拟采用挡土墙进行支护。由于基底碎石土承载力不足,导致挡土墙整体稳定性不满足要求,需采用换填等传统工程措施进行处治,但该方式工期较长、成本较高、安全风险较大、经济性较差。根据项目特点,拟在挡土墙下部设置桩基托梁,以解决承载力不足的问题,即桩基托梁挡土墙支护体系。该项目已完工一年,监测数据反馈水平和竖直方向几乎无变形,整体处于稳定状态,证明了该体系的安全性和适宜性。After leveling in a certain energy storage project in Ceheng County,an unstable soil slope with a height of 10 meters was formed.In order to not affect the normal use of the planned road at the foot of the slope,support design is needed.According to the calculation results of soil pressure,it is planned to use a retaining wall for support.Due to the insufficient bearing capacity of the gravel base,the overall stability of the retaining wall does not meet the requirements.Traditional engineering measures such as replacement filling need to be adopted for treatment,but this method has a long construction period,high cost,significant safety risks,and poor economic efficiency.Based on the project characteristics,it is proposed to install pile cap beams at the lower part of the retaining wall to address the issue of inadequate bearing capacity,forming a system of pile cap beam retaining wall support.The project has been completed for one year,monitoring data show almost no deformation in both horizontal and vertical directions,indicating overall stability and proving the safety and suitability of this system.
