摘要
介绍了自行研制的裂隙介质溶质运移试验测试系统,与国内外同类试验装置相比,该测试系统可以对不同尺寸的裂隙介质进行溶质运移试验,在裂隙介质中布设了测试流体压力、温度、浓度的传感器,可以对原样裂隙中各点的溶液浓度进行直接测量,以此来获得溶质在裂隙介质中的运移规律。应用该测试系统进行了NaCl示踪剂溶液在裂隙介质中运移的试验,并用解析–优化方法求解了裂隙介质中NaCl示踪剂溶液运移的水动力弥散参数。
A testing system, designed by the authors, of solute transport in fractured media is introduced. With this testing system, solute transport experiments can be carried out in fractured media of different scales. Pressure, temperature and concentration sensors are installed in fractured media, which can directly measure solution concentration anywhere in natural fractures. Solute transport experiments are carried out by the testing system with NaCl tracer solution, and hydrodynamic dispersion parameters of NaCl tracer transport are solved by analysis-optimization method.
