摘　　要：常规的物探方法探测地下水体存在多解性问题的根本原因是常规物探方法不能捕捉到地下水体补给、径流、排泄过程中与周围地质体随时发生物质交换并被地磁磁化后形成磁流体的动态信息.本研究假定地下水体是在磁场中均一流动的,在此基础上推导了水体的电阻率是与其速度成负相关的公式.并以此为基础,在室内实验模拟不同溶液以不同速度通过磁场后测电阻率的变化情况.其结果与公式推导一致.地下磁流体对地下水的探测原理就建在此基础上.它打破了物探领域的只有三维信息的捕捉,增加时间维度的地下水体的动态信息捕捉,从而一定程度解决了地下水体探测的多解性问题.Accurate detection of groundwater is to look for water sources,such as mine water and water management are an important factor.The conventional geophysical methods detect groundwater exist multiple solutions of the problem.The fundamental reason is that conventional geophysical methods can not capture the groundwater recharge,runoff and discharge process occurs with the surrounding geological material at any time after the exchange was the formation of magnetic fluid magnetic magnetic dynamic information.This study assumes that groundwater is flowing in the magnetic field homogeneity.On this basis,derived resistivity of water is negatively correlated with the velocity of the form la.And to do this based on laboratory simulation speed of different solutions at different magnetic field measured by the change of resistivity.As a result,consistent with the formula.Ground magnetic fluid on the groundwater detection theory was constructed on this basis.It broke the only three-dimensional geophysical fields of information capture,and increase the time dimension of the groundwater capture of dynamic information.To some extent resolved detection of multiple solutions for groundwater issues.
