This paper emphasizes the inferential structure of the Bayesian model and its implications. The paper shows that for a short historical data base, the conventional method (such as the I'oisson model with deterministic occurrence rate) neglects the uncertainty associated with the model parameters and hence does not provide reliable results. The proposed Bayesian formulation cosiders the statistical uncertainty in the estimation of parameters provides a flexible means of combining information from different sources,...

This paper emphasizes the inferential structure of the Bayesian model and its implications. The paper shows that for a short historical data base, the conventional method (such as the I'oisson model with deterministic occurrence rate) neglects the uncertainty associated with the model parameters and hence does not provide reliable results. The proposed Bayesian formulation cosiders the statistical uncertainty in the estimation of parameters provides a flexible means of combining information from different sources, and gives logically consistent and reasonable estimate of seismic hazard. The paper also includes simple numerical examples for illustration.

本文重点讨论贝叶斯模型的推理结构及其在地震危险性分析中的意义。当历史记录较少时,用定值参数的常用模型(如,用确定平均发生率的泊松模型)不能给出危险性的合理估计。贝叶斯模型考虑了参数本身的不确定性,且能灵活地结合来自地震地质的信息,给出逻辑上一致的危险性估计。本文还提供了把地震地质证据和统计资料结合起来的具体力法,并附有简单列子作为说明。

In this paper it has been found that there is a log-linear relationship between the response intensities and relevant occurrence frequencies at different engineering sites by analysing the occurrence frequency distribution of the response intensities of eight engineering sites in Langfang, Wanzhuang, Tongbai, Qianan, Xinzhuang, Leting and Wangtan of Hebei Province, and Jiangyen of Jiangsu Province. Based on this log-linear relationship, the average yearly rate of occurrence for various intensities at an engineering site can be estimated and then the intensities which might be met with during the coming 50 or 100 years can be forecasted. The forecasting results are quite similar to that of fundamental intensity zoning and seismic risk analysis. Therefore, so long as there are enough historical seismic data in the areas where engineering undertakings are projected, seismic risks of engineering sites can be evaluated by using the frequency distribution characteristics of response intensity.

本文通过对河北省廊坊、万庄、桐柏、迁安、新庄、乐亭、王滩,江苏省江阴等八个工程场地影响烈度的频次分布情况进行分析,发现工程场地的影响烈度与相应频次之间存在对数直线关系。根据这种对数直线关系可以得到工程场地各烈度的年平均发生率,进而可以对场地在未来50年、100年可能遭遇到的烈度进行预测。其预测结果与烈度复核和地震危险性分析的结果是十分相近的。因此,只要工程场地所在地区有足够多的历史地震资料,就可以利用场地影响烈度的频次分布特征来评价工程场地的地震危险性。
