| 摘 要： | 利用数值模拟与含水层垂向应力反演的方法,对降雨与河流荷载作用下静乐井区应力进行定量计算,并从区域应力场与同一构造区其他前兆测项变化特征对2种方法计算结果进行分析。数值模拟结果显示,降雨与河流荷载的共同作用使静乐井所在区域产生的最大垂向位移约为0.7mm,最大垂向应力约为30hPa;同时段静乐井-含水层垂向应力反演结果显示静乐井-含水层最大垂向应力约为79hPa;数值模拟与静乐井-含水层垂向应力反演结果均表明,静乐井水位高值异常与同时段降雨量增多、河流荷载效应增强关系密切,但2种结果存在一定差异。通过可反映井区应力场变化特征的山西地震带3级地震缺震和b值、穿过静乐井的GPS基线、地震矩释放、同一构造单元同时段其他前兆测项与静乐井水位高值异常对比等分析结果可知,2017年静乐井水位高值异常期间井区应力场存在显著异常,推测静乐井水位高值异常除受降雨与河流荷载作用的影响外,也可能受构造活动增强的影响。

| Abstract: | Based on the investigation on the current situation of brick-wood structure houses in rural areas of Hanzhong, this study analyzed the structure types, pattern of Design and Construction, construction locations, foundation treatment measures and the in base forms, and the villagers'' safety awareness in earthquake and the seismic resistance methods. In addition, it introduced and analyzed the damage rules, damage causes and main effect factors, by referring to the earthquake damage information and related literature and also proposed the treatment methods, the recommendations and the countermeasures for the brick-wood structure houses in Hanzhong. |
