摘要
花岗岩裂隙所形成的大量"通道"为地下水中各溶质运移提供条件,研究溶质在裂隙中的运移规律可为地下水污染治理、海水入侵等问题提供理论数据。本次试验使用自制花岗岩裂隙溶质运移试验设备,运用动态试验的方法,研究以Na Cl溶液为示踪剂在花岗岩中运移规律,细致描述分析迁移时间、迁移距离、迁移方向对示踪剂在裂隙中的运移影响,并通过配线求出纵、横向弥散度,为试验提供数据支持。
A large number of ＂channels＂in the granite fracture provide the condition for solute transport in groundwater. The study on the transport law of solute in fracture can provide theoretical data for such problems as groundwater pollution control,water intrusion of the migration of groundwater pollution. The test used a laboratory equipment of solute transport in fractured media designed by the authors,and applied the method of dynamic test to study the migration characteristics of Na Cl in fracture of granite rock.It carefully analyzed the influence of time,distance and direction of transport on the meter in fracture,and got the longitudinal and horizontal disperse coefficient which can provide data support for test.
