Advised Measurement Approach 

 

In  order  to  locate  accurately,  judge  the  location  of  the  abnormal  ground  point,  generally  using 

lining rope as straight line, carry out paint markers at the beginning or middle position, so that find 

the corresponding position according to the test results of graph after measuring. 

 

 

Cross Method 

 

 

 

Grid Method
