This paper relates to some problems about the determination of design ground motion parameters , which include the choice of the attenuation relationship of rock horizontal acceleration response spectrum , the impact of focal depth to rock peak horizontal acceleration and rock response spectrum curves , the choice of intensity envelops function and random input phase , the choice of soil nonlinearity and shear wave velocity , scale of design ground motion response spectrum etc . in the researches of relative aspect , based on a typical section plane of the engineering site , influence of the change of some parameters on design ground motion parameters and the existing errors and corresponding rules are studied by using the method of one dimension model of equivalent linearization
摘要研究了确定设计地震动参数中涉及的若干问题，其中包括基岩水平加速度反应谱衰减关系的选择、震源深度对基岩水平加速度峰值及基岩反应谱曲线的影响、强度包络线函数及输入随机相位的选择、土体非线性特性参数和土层剪切波速值的选择、设计地震动反应谱的标定等问题。
There were troubles in the continuity of the function and of its - derivative divided by band - mass on the boundary . in the theoretical calculation , the wave function is relative to the physical properties of the impurity greatly , the envelop function f ( x , y ) is expanded in terms of the one - dimensional linear harmonic oscillator function in this paper . it satisfies the continuity of the function and of its - derivative divided by the band - mass , so it improves the precision of the function and binding energy
与以往工作不同的是，以前选用的x ， y方向电子的包络函数f ( x ， y )是一维有限深量子阱中波函数的乘积，在边界上波函数的连续性和粒子流的守恒条件存在问题；而在理论计算中，波函数的选取与杂质的物理性质有密切关系，本文选取的电子的包络函数是用一维线性谐振子的波函数展开而成的，在边界上能够同时满足波函数的连续性及粒子流( 1 / m ~ * ) f ' ( x , y )的守恒条件，从而使得波函数和束缚能的精确度得到了改进。
The envelop functions of ground motion for the small - moderate earthquakes in the near - source field are different with those of the larger earthquakes . there are not stationary part any more in the envelop function of these ground motions . after we analyze the characteristics of these envelope functions we take a exponent function instead the three part function
近场的中小地震由于其在到震源的距离与震级方面的特殊性，其时程包络函数的形状与远震、大震有很大的区别，在远震、大震包络函数中很常见的平稳段不再存在。
