高密度电阻率法

1、实验二 高密度电阻率法实验一、 实验目的及要求在学习了高密度电阻率法的理论知识后，为了更好地理解其有关内容及特点，设计本次实验。要求认真复习所学过的相关课本内容，并认真做好实验的每一个步骤。二、 实验器材1. 仪器：duk-2a高密度电法测量系统一套（dzd-6a主机、120道电极转换器、各种接口的连接线）2. 其他材料：电池箱一组，30道的大线（两条）、配套电极（60根）、锤子若干、导线、万用表等。三、 实验的装置类型选择1. 装置类型的选择因课时所限，本实验仅采用温纳装置和施贝测深装置，最大隔离系数设置为15.2. 装置方式，本次实验共采用两种装置型式进行测量。温纳装置：电极排列规律是：a

2、，m，n，b（其中a，b是供电电极，m，n是测量电极），am=mn=nb为一个电极间距，随着间隔系数n由n（min）逐渐增大到n（max），四个电极之间的间距也均匀拉开。该装置适用于固定断面扫描测量，其特点是测量断面为倒梯形，电极排列如下：图1 温纳装置电极排列示意图施贝测深装置：该装置适用于变断面连续滚动扫描测量，测量时，m、n不动，a逐点向左移动，同时b逐点向右移动，得到一条滚动线；接着a、m、n、b同时向右移动一个电极，m、n不动，a逐点向左移动，同时b逐点向右移动，得到另一条滚动线；这样不断滚动测量下去，得到矩形断面。其电极排列如下：图2 施贝测深装置电极排列示意图四、 实验过程及实验

3、数据1. 首先由实验指导老师对实验仪器及操作方法进行仔细的介绍，对其连接方法进行示范。2. 将相关仪器设备运送到实验场地，首先按5m道间距沿直线布设60根电极，同时如果需要无穷远线由部分学生去放无穷远线。3. 连接电路，设置参数如下：隔离系数：1-15，供电脉宽：0.5ms，供电周期1ms。4. 首先检查电极的接地电阻，如果接地电阻过大要对相对应的电极进行处理，此过程有时要重复若干次至到满足接地条件再进行测量。5. 观测数据：测量过程中观测dzd-6a主机测量数据的排列规律，观测电极转换器屏幕上电极排列以及变化规律。五、 实验数据的处理及解释1. 数据的整理 施贝装置序号序号序号112.943
