【摘要】 本文求出了以斜角坐标定义的两相条交断层为坐标轴,用弹性地基板定义岩石圈的斜交板弯曲振动方程的解。以此计算距断层较远的垂直地震力,又结合断裂力学,给出计算失稳破裂前断层端部应力强度因子及失稳破裂后地震释放的能量,以及断层两侧产生的相对位移及地震矩的计算公式。更多还原

【Abstract】 In this paper we have obtained the solutions of the bending vibration for a slant plate between two intersected faults.The governing equation of the plate takes these two straight lines (the faults) for its coordinates.For the part of the plate which is far enough from the faults,its vertical earthquake component may be calculated by these solutions,and for the other part of the plate which is near the fault’s zone,the fracture effect must be considered,and so we apply methods of fracture mechanics to give the following formulae,the stress intensity factors before earthquake rupture occurrence,the amount of released strain energy,the relative displacement between the two sides of a fault and the seismic moment after the earthquake rupture occurrence.更多还原
