深圳地应力状态及其区域稳定性评价

作者通过地应力测量、模拟、实验、应力场分析等一系列测试研究工作，确认深圳现今应力状态以水平应力场为主，优势方向为北西向，最大主压应力值2．6MPa，最大剪应力值0．37MPa，其中半数测孔水平面上的地应力呈等值状态，无明显应力集中现象。表明其地壳活动较弱、区域稳定性良好。

GEOSTRESS STATE AND REGIONAL STABILITY ASSASSMENT OF SHENZHEN

Shenzhen City of Guangdong Province, one of the special districts open to the outside world, is a new-emerging and modernized city. Thr Wuhua-shenzhen fault of Lianhuashan mobile belt goes through the city. So the regional stability of Shenzhen is the key to the development of the city, and should be stidied and scientifically assessed. During 1985-1987, a series of analyses and survey such as geostress survey, simulation experiment and stress field analysis have been made. And the results show that the geostress state of Shenzhen is predominantly of horizontal stresses and the maximum principal compressive stress value of 2.6 MPa and a similar value of the minimum principal stress as well as a low maximum shear stress value of 0-0.37Mpa.
