1) present tectonic stress
现今构造应力
1.
And the direction of present tectonic stress was the same as that of ancient one.
以山西晋城成庄煤矿区为例,根据历史构造作用留下的褶皱、节理、断裂等构造形迹,建立构造格架,推断晋城成庄矿区历史上曾发生先南北向、后东西向的两期大的构造运动,古构造作用为先东西向加载60MPa,再南北向加载110 MPa,现今构造应力是与古构造应力方向一致。
2) present tectonic stress field
现今构造应力场
1.
The present tectonic stress field in the head area of the Three Gorges reservoir was systematically analyzed and verified in the geological,seismological,deformation and in situ stress contexts and checked by numerical modeling.
本文从地质、地震、形变、地应力测量等方面对三峡库首区现今构造应力场进行了系统的分析和论证,并用数值模拟进行了验证,认为三峡库首区现今构造应力场属于纯剪切变形体制,即:在来自西部NE—SW方向主压应力挤压的基础上,同时叠加有因江汉—洞庭盆地拉张而引起的NWW—SEE向主张应力的作用,这两种力源近于直交,可以分别作为研究区现今构造应力场的主压应力(1σ)和主张应力(σ3)。
2.
According to the displacement and strain field obtained by GPS in 1992 and 1995 and combining with the abundant geologic data, the present tectonic stress field in North China, as a plane strain problem, is simulated numerically by means of the finite element method.
根据１９９２年和１９９５年两期ＧＰＳ测量结果所获得的位移场和应变场，结合丰富的地质资料，利用有限元方法对华北地区现今构造应力场进行了数值模拟。
3) determination of current structural stress field characteristics
现今构造应力场特征判定
4) present ground stress
现今地应力
1.
Study on the present ground stress of Es_3~中 in Niu 35 fault block;
牛35块沙河街组三段Es_3~中现今地应力研究
2.

纯41断块沙四段现今地应力场有限元模拟
6) in-situ stress
现今地应力
1.
Using the measured stress data(fracturing method,AE method) as constrained conditions,the plane and profiles of stress distribution and characteristics of the simulated area was calculated using finite element in-situ stress field simulation.
在综合考虑模拟区几何模型的形状及大小、区域构造格架、边界条件的情况下,选择与地质构造相适应的力学模型,并以实测地应力(压裂法、声发射法)为约束条件,利用有限元现今地应力场模拟方法计算了模拟区地应力场的平面和剖面展布及其特征,模拟结果可为生产单位科学开发管理油气藏提供参考。
