- To obtain the stress level at the earthquake source , this paper sets forth the solution of the stress magnitude at the earthquake source by seismic stress drop and the stress axis deflections before and after large earthquakes
摘要为求解震源处应力量值,运用大地震造成的应力方向偏转和地震应力降给出了求取震源处应力大小的方法。 - The pre - seismic and post - seismic stress direction can be statistically determined by a large collection of foreshock and aftershock focal mechanism data while the stress drop can be determined through the source fracture inversion from seismic wave data or crust deformation data
地震前后的应力方向可根据大量前震和余震震源机制统计给出;地震应力降可通过地震波或地壳形变资料的震源破裂反演研究得到。 - The stability of the section of the ash dam situated in a seismic zone for matou power plant is analyzed with the total seismic stress approach of shear strength herein , and then the engineering measures to enhance the seismic stability of the dam are studied as well ; which can provide a reference basis for the seismic design of the dam

通过对比有限元计算结果和试验数据,分析得出塑料土工格栅筋材的最大动拉应力的分布与静拉应力的分布沿筋材的埋深大致相同,只是应力的值大小不同;地震作用下土筋间的动似摩擦系数是随地震加速度的增加而减小;模型沿墙高方向的加速度响应等。接着,根据模型动力有限元时程分析结果和模型试验数据的比较分析,得出由土体单元、接触单元和筋材单元组合的塑料土工格栅加筋土非线性动力有限元分析模式的合理性。 - The plane - wave analytic solution of the coupled fluid - air - solid system and the fem model of air cushion isolations are applied to study the influence of air cushion on earthquake response of dams . the calculations show that air isolation will reduce the hydrodynamic pressure significantly and restrain the dam vibrations during earthquakes . if the dam and reservoir is isolated by air cushions , it will decrease the hydrodynamic pressures by more than 90 % and the seismic stresses by 20 - 30 %
