摘　　要：人类频繁工程活动形成的人工切坡容易诱发崩塌、滑坡等地质灾害。本文在对粤北山区开展地质灾害风险调查评价的基础上,分析区内人工切坡及其崩塌的发育特征,提出有针对性的防治措施建议,并以区内典型崩塌点为案例,评价了灾害点在不同工况下的稳定性。Artificial cutting slopes formed by frequent human engineering activities are prone to induce geological disasters such as collapse and landslide.Based on the investigation and evaluation of geological disaster risk in the mountainous area of northerm Guangdong Province,this paper analyzes the development characteristics of artificial cutting slopes and their collapses in the area,puts forward targeted proposals for prevention and control measures,and evaluates the stability of the disaster points under different working conditions by taking the typical collapses in the area as a case.
