浅埋桩基的高密度电法数值模拟与探测OA

When a new building is to be rebuilt on the demolished building,it is necessary to remove the building foundation left in the site in order to facilitate the foundation pile construction and foundation pit excavation.in the absence of relevant data,the exploration of foundation piles in the land has always been a difficult problem.In this paper,the corresponding mathematical model is established by finite difference technique,and the forward simulation of high-density electrical method is carried out.On the basis of forward simulation,the high-density electrical method is used to detect the underground pile,and the position of the foundation pile is verified by the drilling magnetic gradient method.The magnetic gradient verification shows that the high-density electrical method is feasible to detect the shallow buried pile foundation without basic data.
