| 摘 要： | 2008年5月12日汶川M_s8.0级地震地表破裂迹线周围建筑物倒塌率非常之高,导致重大的人员伤亡,举世震惊.为了避免历史悲剧重演,沿地表破裂迹线周围建筑物重建时,必须确定一个合适的避让距离.本文依据现场科考地表破裂带宽度、建筑物完全倒塌宽度、倒塌率与断层距之间的关系,联合未来一段时间范围内断层地震危险性分析、地表破裂迹线永久位移分布模式,建立完全倒塌与断层距之间的关系.提出了几种情况下的汶川M_s8.0级地震地表迹线处建筑物重建应考虑的避让距离.

| Abstract: | The Ms 8.0 Wenchuan earthquake caused high rate collapse of buildings near the trace of surface rupture and inflicted serious casualties.To avoid repeating of the tragedy,a setback distance should be determined in reconstruction along the trace of surface rupture.Based on the dislocations at the rupture point,the width of the surface rupture and the width of building total collapse originated from field investigation,the relationships among them are established.With the probabilistic approach to evaluate th... |
