德阳地区某堰塘东岸滑坡稳定性分析及防治

Stability Analysis and Prevention Programs on the Landslip in the East Coast of a Small Reservoir in Deyang District

在对德阳地区某堰塘东岸滑坡的地质地貌条件及变形迹象进行深入调查的基础上,对该滑坡的主要成因及稳定性进行了分析与评价,并有针对性地提出了工程防治方案。研究表明,疏松透水的土层、较强的降雨以及人类的耕作活动是导致滑坡发生的主要因素。在天然状态及天然+地震状态下,该滑坡基本稳定;在连续高强度降雨状态下,该滑坡欠稳定。故采取截、排水及抗滑桩等工程措施是防治该滑坡的有效方案。

On basis of in-depth investigations on geological and geomorphological conditions and deformation signs of the landslip in the east coast of a small reservoir in Deyang district,the paper analyzes and evaluates the causes and stability of the landslip,and well targeted raises the prevention programs.Studies have shown that the loose permeable soil layer,strong rainfall and human farming activities are the main factors leading to landslip.In natural and earthquake state,the landslip is stable,but under the condition of the continuous heavy rain,the landslip is not stable.To take the engineering measures such as interception,drainage and anti-slide pile are the effective programs on prevention and treatment of the landslip.
