贵州西部地区农村民居抗震性能及震害分析——以威宁县为例

Analysis of anti-seismic performance and earthquake damage of rural residential houses in western Guizhou Province:a case study on Weining County

贵州位于南北地震带南端,近年来发震的频度和强度均处于我国平均水准之上。为了解贵州西部地区农村民居的抗震性能及震害情况,本文以地震密度和强度均较大的威宁县为例,通过实地调研,深入研究该地区农村民居抗震设防问题,分析总结该地区农村民居主要结构类型的抗震能力及遭受地震时可能发生的震害情况,并提出如何加强农村民居抗震设防的建议。

Guizhou is located at the southern end of the North-South Seismic Belt.In recent years,the frequency and intensity of earthquakes occurred in Guizhou are above the average level of China.In order to understand the anti-seismic performance and earthquake damage of rural residential houses in western Guizhou,this paper takes Weining County as the study area.The anti-seismic capacity of the main structure types of the rural residential houses in the area and the damage that may occur in the event of an earthquake are analyzed,and suggestions on how to strengthen the anti-seismic performance of rural residential houses are put forward.
