【摘要】 b值和ν4是地震安全性评价工作中进行地震危险性概率计算的两个重要参数,其取值是否合理将影响地震危险性计算结果的合理性。本文采取两种不同的计算方法对重庆地区的b值和ν4进行计算,并对于这两个参数进行了讨论.我们认为取b=1.19和ν4=2.48基本上是合理的,该结果对重庆地区开展地震安全性评价工作和地震中长期预报工作具有一定的参考价值。更多还原

【Abstract】 The b-value and ν4-value are two important parameters in the calculation of disaster analysis in the evaluation of safety for engineering sites.The rationality of b-value and ν4-value decide the rationality of disaster analysis.This paper introduces two methods to evaluate b-value and ν4-value,contrasting and discussing the value of b-value and ν4-value.Our results will have important reference value for carrying on seismic safety evaluation and earthquake predication in Chongqing Province.更多还原
