城市震害时空序列的展开过程分析

ANALYSIS ON TIME-SPACE SEQUENCE FOR URBAN SEISMIC DISASTER

本文系统地介绍城市地震灾害的主体，震害的特征及按时间、空间序列的发展过程。城市震害是多种灾害同时发生、相互影响，并且多种灾害在时空序列上都有发生、发展和延续的过程。通过对以往几次城市地震灾害的现象的研究、展示其在时空序列的分布规律。

In this paper the main body of seismic disaster in urban area and its characteristics and the developing alignment on the time space sequence are discussed.In city,there are various types of seismic damages which are influence each other.All of the damages undergo the occurence,developing and continuing process.Based on the analysis on seismic damages during the earthquakes occured in urban areas,this paper make an effort to reveal the distributing pattern of damages on time space sequence,and seek for the relations between various damages and relief actions by using the means of statistics and system engineering.
