湖北省宜昌市猇亭区人类工程活动与城市地质灾害
Engineering Activities and Urban Geological Disasters at Xiaoting District in Yichang City, Hubei Province
摘要
Abstract
[Objective] The aim of the study is to investigate the relationships between engineering activities and urban geological disasters,and provide help for the urban planning and construction.[Methods] Based on the on-site geological environment survey(geological exploration,geological surveying and mapping),we studied the geological disasters caused by engineering activities at Xiaoting District in Yichang City,Hubei Province and probed into the internal and external factors causing these disasters.[Results] Artificial excavation was the main cause of potential landslides on unstable slopes.Artificial refilling is the main cause of landslides with a potential to develop into debris flow.Geological disaster related to the expansive clay soil are also closely related to engineering activities.The excavation in road construction leads expansive clay soil to be unstable and to swell under the impact of rainfall,thus causing the road and steep slope deformation and failure.[Conclusion] The engineering activities are the main external factors causing the geological disasters.The flat,laminated and loose structure of the rock and soil mass,and the distribution of expansive clay soil are the internal factors of geological disasters.关键词
