基于贵州省某岩土边坡变形的监测分析
|
摘要
边坡工程的监测工作具有监测内容多、信息量大、工程复杂等特点。根据监测报告,以贵州省某电厂主体工程附近的边坡为例,通过对岩土边坡进行监测分析其变形特性,从宏观观测现象分析、监测位移趋势分析两个方面研究边坡滑坡变形特征。边坡监测数据表明,边坡不同蠕滑变形阶段有着不同变形演化特征;影响该滑坡变形因子主要有施工过程、边坡支护的方案选择、边坡周边环境及工程地质的水文条件。同时,根据边坡位移–时序曲线切线监测数据分析日位移速率,对其他相似工程有借鉴意义。
The monitoring work of slope engineering has many characteristics such as monitoring content,large amount of information and complicated engineering.Based on the monitoring report,this paper takes the slope near the main project of a power plant in Guizhou Province as an example to analyze the deformation characteristics of the rock and soil slope.From the aspects of macroscopic observation phenomenon analysis and monitoring displacement trend analysis,the deformation characteristics of slope landslide are studied.The slope monitoring data shows that the different creep deformation stages of the slope have different deformation evolution characteristics; the deformation factors affecting the landslide mainly include the construction process,the choice of slope support scheme,the surrounding environment of the slope and the hydrological conditions of engineering geology.According to the slope displacement-time series curve tangent monitoring data,the daily displacement rate is analyzed,which can be used for reference to other similar projects.
