Abstract:The reliability analysis of 4-component borehole strain data of the six sites in the Chongqing area of the Three Gorges is carried out. The strain parameters of each site is derived using relative calibration, and the local deformation characteristics in this area are obtained. The results show that the borehole strain observation data of the six sites are reliable, and the plane strain of one site is tensional, but the strain of the other five sites near the Three Gorges area is pressured. The direction of the principal strain is consistent with the direction of the regional stress, indicating the pressure characteristics of Chongqing area of the Three Gorges.
