Abstract

Abstract

In order to find out the in-situ stress state near the Penglai coast, hydraulic fracturing in-situ stress measurement was conducted in two boreholes (less than 200 meters in depth). The results were compared with the in-situ stress state of three boreholes off Changdao. Regression analysis was adopted to analyze the variation of in-situ stress with depth in this area. Fault stability in the study area was discussed combined with the ratio (μ_m) of maximum shear stress to average principal stress and lateral pressure coefficient(K'). The results show that the in-situ stress state of the Penglai coast is basically the same with that of Changdao, with the direction of the maximum horizontal principal stress being mainly NEE-EW which is consistent with the regional stress field in north China. The gradient of horizontal stress is greater than the average in-situ stress gradient of Bohai Rim. The relative magnitude of the three-dimensional principal stress in the shallow part of the study area is mainly S_H > S_h > S_v which is conducive to the movements of the reverse faults. The values of both the study area and μ_m are high whose distribution intervals are 2.76~3.98 and 0.47~0.59 respectively. The land area faults and regional stress directions intersect at larger angles and are in a stable state; the angles between the NWW and NE faults of the sea area and the regional stress fields are smaller. If the regional stress continues to increase, it will be conducive to the movements of the strike-slip faults. This may be the primary reason for the frequent earthquakes of Changdao which is consistent with the fact that the focal mechanism of the earthquakes is mainly strike-slip. The research results are of great significance not only to the evaluation of fault stability in the study area but also to the design and construction of major projects.
