摘要
荣昌及周边是重庆地震较活跃的地区,是每年的重点关注对象,因此对荣昌地区的地震风险防控十分重要。根据荣昌地区历史地震分布和断裂分布设定地震,利用重庆地区震害回归曲线估算受灾面积、死亡人口、伤亡人口、倒塌房屋数量和直接经济损失,并与地震应急灾害评估系统计算结果进行比较,同时分析周边几次大地震对荣昌地区的影响,最后对结果进行修正。根据历史地震等震线分布,绘出综合等震线图,给出受灾范围。对不同震级或烈度提出相应的处置建议。
Rongchang and its surrounding areas are seismically active areas in Chongqing City. Risk management is essential to this region. Scenario earthquake is based on the historical earthquake distribution and fault distribution in Rongchang area. According to earthquake damage regression curve in Chongqing area,the affected area,death toll,casualty,the number of collapsed houses and the direct economic loss are estimated. The results are compared with the earthquake emergency disaster assessment system. Meanwhile,the impact of several major earthquakes in Rongchang are taken into account. Finally,results are revised in this paper. According to the distribution of historical isoseismal,the synthetic isoseismal and the disaster area is drawn,as well as the corresponding disposal suggestions for different magnitude or intensity are given.
