城市群地震灾害风险评估方法的一点探索

open access: yesDizhen xuebao, 2022
基于粤港澳大湾区地震灾害风险评估的初步成果,分析了湾区城市群地震环境、承灾体分布和场地特点,提出了两种确定地震输入的设定地震原则,即潜在震源区设定地震原则和最大风险设定地震原则,按照这两种原则可以更加准确地进行城市群地震灾害风险评估。在前人工作的基础上,提出了考虑场地条件影响的地震灾害风险表达式,探索了适合三维模拟非一致激励地震动输入的建筑物和生命线工程灾害风险评估方法,提出了建筑物和生命线工程灾害风险评估中考虑场地影响的思路,为客观地评估城市群地震灾害和损失风险提出了可参考的建议。

相对局部区域震源参数随机不确定性经验关系研究

open access: yesDizhen xuebao, 2021
在进行未来破坏性地震的强地面运动数值模拟时,震源参数选取的准确性对地震动预测的结果影响很大。震源参数的确定存在很多不确定性因素,既包含随机的不确定性因素,又包含认知的不确定性因素。本文在大量地震事件及文献调研的基础上,运用统计学方法对具备随机不确定性特征的震源参数进行统计研究,以震源参数经验公式的形态建立解释其随机性和不确定性的数学模型。为了研究局部地区震源参数的定标关系特征,获得更加适用于局部地震密集区域,尤其是包含中国大陆地区在内的局部区域的震源参数的经验关系,本文从GCMT地震目录中选取了1 ...
