基于监测数据的某库区土质边坡变形原因分析

Analysis of Soil Slope Deformation in a Reservoir Area Based on Monitoring Data

某水利枢纽库岸边坡长期存在明显的土体变形、周边房屋开裂等情况,加上降雨入渗、水库坝前水位涨落的影响,使得边坡稳定性问题更加突出。通过土体表面滑动远程自动化监测,结合传统监测手段,定期对土体和建筑物变形区域进行沉降、水平位移和裂缝开合度观测。收集监测区域的坝前水位、降雨量和地表气温等环境变量数据。分析监测结果,对比各区域土体变形发展与边坡环境变量的关系,探究其变形原因,对滑坡类型进行归类,为类似边坡的监测、分析提供参考。

The bank slope of a water conservancy project has obvious soil deformation,surrounding buildings cracking and other conditions for a long time,coupled with rainfall infiltration,the water level in front of the dam may be affected,making the slope stability problem more prominent. Through the remote automatic monitoring of soil surface sliding,combined with the traditional monitoring means,the settlement,horizontal displacement and crack opening degree of soil and building deformation area are regularly observed. Environmental variables such as water level in front of the dam rainfall and surface temperature were collected. The monitoring results are analyzed to compare the relationship between soil deformation development and slope environmental variables in different regions, explore the causes of deformation, classify landslide types, and provide references for monitoring and analysis of similar slopes.
