南水北调中线工程总干渠穿越焦作矿区段变形监测分析

Deformation Monitoring Analysis of the Main Canal Crossing Jiaozuo Mining Area in the Middle Route of South-to-North Water Diversion Project

在南水北调总干渠穿越煤矿区段建立专用的变形监测系统,监测采空区在施工前、施工期、运行初期的变形情况,通过采集埋设在地表、岩土体内部、地裂缝上的变形监测设施及地下水位观测数据,运用技术手段对总干渠进行稳定性分析研究,评价变形对总干渠的影响并预测发展趋势,为采空区段工程优化设计、施工、运营管理提供可靠的技术依据。

A special deformation monitoring system is established in the section where the main canal of the South-to-North Water Diversion Project crosses the coal mine to monitor the deformation of the goaf before construction,during construction and at the initial stage of operation.By collecting deformation monitoring facilities buried on the surface,inside rock and soil mass,and on ground fissures,and observing data of groundwater level,the stability of the main canal is analyzed and studied by technical means to evaluate the impact of deformation on the main canal and predict the development trend.This provides a reliable technical basis for optimizing the design,construction,and operation management of the goaf section of the project.
