摘　　要：研究区因场地大面积开挖平整,形成一处高6.8~25.8 m、宽约125 m的边坡,边坡由新近系地层的强风化泥岩、中风化泥岩和第四系地层的风积黄土和重力堆积物组成。该边坡在地震、降雨和人类工程活动的影响下稳定性逐渐降低。边坡稳定性评价认定边坡现状稳定性较差,在暴雨、地震等不利工况条件下,失稳的可能性较大。边坡一旦失稳,将影响相关人员生命及财产安全,因此需开展不稳定边坡治理,以消除地质灾害的潜在危害。A slope with a height of 6.8~25.8 m and a width of about 125 m was formed in the study area due to large-scale excavation and leveling,which consists of strongly weathered mudstone and moderately weathered mudstone in Neogene formation,and aeolian loess and gravity deposits in Quaternary formation.The stability of the slope gradually decreases under the influence of earthquake,rainfall and human engineering activities.The slope stability evaluation determined that the current stability of the slope is poor,and the possibility of instability is greater under adverse working conditions such as rainstorm and earthquake.Once the slope is unstable,it will affect the safety of people and property in the area,so it is necessary to carry out unstable slope treatment to eliminate the potential hazards of geological disasters.
