摘　　要：本文在Ｔｕｒｃｏｔｔｅ地壳应力场基本公式的基础上，建立地壳构造应力场定量优化模型．应用重力资料计算绘制了华南、华北、东北地区及塔里木油区１：２００万地壳构造应力场图；并用垂线偏差计算了西欧北海区域构造应力场图，其数量级也符合Ｔｕｒｃｏｔｔｅ计算的实际情况．Based on Turcottes's formulas of crustal stress field, this paper establishes a quantitative optimization model for the tectonic stress field in the crust. The tectonic stress field in the crust in the regions of South China,North China,Northeast China,and Talimu oil field was calculated from gravity data, and corresponding stress maps of 1/2000000 scale were plotted. In adition the stress field in the North Sea region in western Europe was calculated from vertical deflection data,the resulting order of magnitude was in agreement with the calculation of Turcotte.
