摘要
本文以武汉市主城规划区地震动参数小区划(以下简称武汉市地震动参数小区划)工作为主线,研究了弱震区内潜在震源区划分和工程地质条件对峰值加速度的影响程度、软土地基反应谱特征与构造措施的选取,以及以小区划成果作为抗震设防标准在实际应用中所遇到的一些问题。
On the ground motion parameter of microzonation in Wuhan urban planning area this paper introduces the general situation, research method, contents and achievement characteristics of Wuhan microzoation. Studying on the social environment and regional seismic geological environment of Whuan which locates in the middle reach of Yangtze River with weaker seismic activities, this paper analyzes the partition of latent seismic source areas, the impact engineering geology condition on peak acceleration, the choice of response spectrum characteristic and for- mation measure for soft clay ground and some problems when microzonation achievements put into practice.
