【摘要】 利用汶川地震中重庆市部分城镇地区房屋受损情况调查资料,探讨了低设防要求地区乡镇房屋抗震薄弱环节。与以往对高烈度地区房屋严重受损的结构性缺陷研究不同,在发生概率更高的中小地震作用下,低烈度地区房屋受损更能反映乡镇自建房或低设防房屋的抗震薄弱环节。分析了灾区目前村镇建筑在抗震方面存在的问题,提出了适合重庆地区推进村镇房屋抗震设防工作的建议。本研究可以为进一步落实新一代区划图设防要求、有效地避免乡镇地区小震大灾提供科学依据。更多还原

【Abstract】 The weaker links of the buildings in villages and towns in lower earthquake resistance protection areas are discussed according to the investigation data of urban damaged houses in Chongqing by Wenchuan earthquake. The researches are different from the structural defects of severely damaged buildings in high intensity region,the weaker links of buildings in villages and towns are obviously in middle earthquakes in lower intemsity regions. The current prblems of village construction in seismic disaster area are analyzed and suggestion to promote rural houses seismic resistance protection in Chongqing area is put forward. The results can be further applied earthquake resistance protection requirements by new generation of zoning map,and effectively avoid the small earthquake catastrophe in villages and towns region.更多还原
