基于随机场地分析的场地小区划方法

SEISMIC MICROZONATION BASED ON THE CONCEPT OF RANDOM SITE

讨论了目前场地小区划方法中存在的问题,指出应用后验贝叶斯方法估计场地物理参数和进行随机场地地震反应分析的必要性,提出了基于随机场地的场地小区划方法。通过实际应用,表明本方法是可行实用的。

This paper puts forward a new method of seismic microzonation which is based on the concept of random site. Some problems in the common method of seismic microzonation are discussed. It is suggested that is necessary to estimate the site parameters by means of empirical Bayes estimation, and to analyse the earthquake response of site by the dynamic analysis of random structures. According to practice use. the method is reasonable and feasible.
