淠史杭灌区膨胀土渠道总长约1400km,滑坡总处数198处,长度超过16km,为有效控制滑坡的发生、发展和整治,2004年10月安徽省水利厅立项开展了“膨胀土滑坡机理与防治技术研究应用”的科研课题。项目由安徽省淠史杭灌区管理总局和合肥工业大学共同承担。课题组对淠史杭灌区渠道滑坡进行了系统的调查研究,通过室内和现场试验、理论分析,剖析了膨胀土河渠滑坡机理,研究了河渠滑坡防治技术,提出了膨胀土滑坡治理的计算方法,为工程设计提供技术支撑。通过野外调查和现场勘测,收集了灌区膨胀土边坡资料,开发了淠
The total length of the expansive soil canal in Pishihang Irrigation Area is about 1400km with 198 landslides and a total length of over 16km. In order to effectively control the occurrence, development and remediation of the landslide, the Anhui Provincial Department of Water Resources in October 2004 initiated the “Expansive Soil Landslide Mechanism And prevention and control technology research and application ”research project. The project is jointly undertaken by Anhui Provincial Pishihang Irrigation District Administration and Hefei University of Technology. The research team systematically investigated and studied the canal landslides in the Pishihang Irrigation Area. By means of laboratory and field tests and theoretical analysis, the mechanism of landslides in expansive soil and river channels was analyzed. The prevention and treatment techniques of river channels and landslides were studied. Provide technical support for engineering design. Through field investigation and field survey, the information of expansive soil slope in irrigation area was collected and developed
