示踪试验分析方法在地下工程水害治理中的应用研究

 为查明地下水补给与运移规律，指导地下工程涌水注浆治理设计与施工，将用于大区域水文特征研究的水文示踪试验方法引入到地下工程涌水治理中。研究紫外光谱扫描精确测定超低浓度有色示踪剂的试验方法与数据分析技术，提出地下工程涌水区域的水力连通时间、补给相关系数、裂隙空间体积、地下水流速及压力等水文信息的获取方法；基于水文示踪试验数据分析结果，建立注浆治理中注浆材料选择依据与注浆参数确定方法。以某铁矿涌水工程治理为例，详细阐述水文示踪试验在涌水工程治理中的应用方法、数据处理过程及应用效果，希望对类似工程具有一定的借鉴意义。

RESEARCH ON APPLICATION OF TRACER EXPERIMENT ANALYSIS METHOD TO WATER HAZARDS MANAGEMENT IN UNDERGROUND ENGINEERING

To identify groundwater recharge and migration rules and guide the grouting treatment design and construction of water gushing underground engineering,tracer experiment for the hydraulic characteristics research of large area is introduced into the gushing-water underground engineering control.Base on the ultraviolet spectroscopy scanning method of low concentrations of colored tracer and data analysis technology,acquisition method of hydrological information(hydraulic connection time,the correlation coefficient of recharge,fracture space volume,groundwater flow rate and pressure) is proposed.According to the analysis of the tracer experiment result,choice of grouting material and determination of the grouting parameters can be put forward.Taking an iron ore for example,tracer experiment(application methods,data processing and application results) in gushing-water engineering control is described detailly,which is supposed as a reference to similar engineering.
