| 摘 要： | 在汶川地震作用下,北川县城的建筑物遭到严重损毁.为给北川县及邻近区县防灾规划和工程抗震设防提供科学参考,本次研究在现场实地调查的基础上,对北川县城建筑物损毁机制与县城地质条件之间的关系进行分析,结果表明,北川县城建筑物损毁是由地表破裂、滑坡、崩塌、地表震动等多种破坏机制综合作用的结果.结论:在北川及邻近区县防灾规划中,建筑物的修建应尽量避开断裂展布带、崩滑灾害易发区段等可能对建筑物造成毁灭性破坏的区域,对于已建成区附近的灾害易发点也应采取必要的工程措施加于防治.

| Abstract: | The buildings were severely damaged in Beichuan County because of the Wenchuan earthquake action. In order to provide scientific foundation for prevention earthquake plans and future design of earthquake - resistant structures, the research is based on field survey data, and the relationship between failure mechanism of buildings and geological conditions in Beichuan County was analyzed. The failure of buildings in Beichuan County resulted from the joint effects of surface rupture, ings should keep clear of fault zone and collapse landslide, collapse and ground vibration. Therefore, the build- - slide zone, engineering measures was taken in geological hazard zone near the built -up area. |
