【摘要】 本文导出了一种给出相对烈度在lg R~0之间的收敛解(忽略震级)的小震方程式。结合在贝加尔地区岩石抗震特性调查与文字资料和统一理论,使人们可对震源等势面进行评估。确定了在震源区边界处的地震烈度稳定性和弹性波在地壳中的传播,使得推导出从地震主要参数震级向随震中距不同的烈度定量计算的转换成为可能。获得了烈度(能通量的密度)对距离的双线性相关,给出了能通量密度和相对烈度之间的关系。求出了取决于地表建筑地基的物理特性的振动载荷烈度。在地震学角度,这种强震的定量预测方法是一种提供详细地震区划和场地小区划的可能手段之一。更多还原

【Abstract】 The macroseismic equation,giving the convergent solution(regardless of magnitude) for relative intensity at lg R~0,was derived. Investigation of seismically resistant characteristics of rocks in the Baikal region together with literary data and unified theory allowed one to evaluate the equipotential source surface. The constancy of earthquake intensity at the boundary of a source,the radiator of elastic waves in the crust,is established. This made it possible to carry out transition from the main parameter of an earthquake,the magnitude,to the quantitative calculation of intensity with distance from a source. Bilinear dependence of intensity(density of energy flux) on a distance is obtained. Correlation between density of energy flux and relative intensity is given. Intensity of oscillatory loads depending on physical characteristics of grounds-building bases was derived. The proposed method of quantitative prediction of large seismic effects in seismological aspect is one of the possible methods to provide the detailed seismic zoning and microzoning of the territories.更多还原
