根据已获得的最新 Ｇ Ｐ Ｓ 观测资料，利用有限元方法反演华北地区现今构造应力场。反演结果表明，华北地区现今构造应力场除受５５°～２３５°方向的压应力外，同时还受到１４０°～３２０°方向的拉应力，其中 Ｎ Ｅ－ Ｓ Ｗ 向的压应力最大，约为 Ｓ Ｅ－ Ｎ Ｗ 向的２ 倍。认为这一应力场是２ 种动力学过程的叠加，一是印度板块和太平洋板块的挤压，其中来自印度洋板块的作用力最大，约为太平洋板块作用力的１ ．５ 倍；另一个是因地幔隆起而产生的 Ｎ Ｗ － Ｓ Ｅ 向水平拉张力
Based on the latest GPS observations obtained, the present tectonic stress field in North China is retrieved using the finite element method. The inversion results show that the present tectonic stress field in North China is subject to compressive stress in the direction of 55 ° ~ 235 ° and tensile stress in the direction of 140 ° ~ 320 °, of which compressive stress in the N E-S W direction is the largest and about Twice as many as S E- N W. It is considered that this stress field is a superposition of two kinds of dynamic processes. One is the compression of the Indian plate and the Pacific plate, of which the force from the Indian Ocean plate is the largest, which is about 1 in the Pacific plate. 5 times; the other is N W - S E due to mantle uplift to the horizontal tension
