黄土地区生土建筑震害特征及防灾对策研究

生土建筑在我国黄土地区广大农村仍占相当比例，历次地震，房屋破坏严重。因此，加强对黄土生土建筑抗震性能的研究具有重要意义。通过对陕、甘、宁、青、晋等省(区)黄土生土建筑民房的现场调查，将黄土地区生土建筑划分为5种类型，阐述了其结构特点。根据黄土地区地震中生土建筑的破坏情况，阐述了不同类型生土建筑的震害特征及致灾机理，并对其在不同地震烈度下的震害结果进行了统计分析，给出了各类生土建筑在地震烈度Ⅵ—Ⅹ情况下的震害预测结果。在此基础上，针对当前民房建设中抗震设防存在的问题，提出了相应的预防对策。     

The 2011 flood event in the Mekong Delta: preparedness,response, damage and recovery of private households and small businesses

Floods frequently cause substantial economic and human losses, particularly in developing countries. For the development of sound flood risk management schemes that reduce flood consequences, detailed insights into the different components of the flood risk management cycle, such as preparedness, response, flood impact analyses and recovery, are needed. However, such detailed insights are often lacking: commonly, only (aggregated) data on direct flood damage are available. Other damage categories such as losses owing to the disruption of production processes are usually not considered, resulting in incomplete risk assessments and possibly inappropriate recommendations for risk management. In this paper, data from 858 face‐to‐face interviews among flood‐prone households and small businesses in Can Tho city in the Vietnamese Mekong Delta are presented to gain better insights into the damage caused by the 2011 flood event and its management by households and businesses.     

遥感震害快速定量评估方法及其在玉树地震中的应用

在伽师地震、汶川地震遥感定量化灾害评估基础上,提出了基于少量现场调查样本进行遥感解译震害与地面实际震害定量评估的方法,以玉树地震为例,建立了遥感解译震害与现场调查结果的定量关系,并进一步得到了玉树县城结古镇街区的等效震害指数和结古镇综合震害指数,结果显示遥感震害快速定量评估结果与实际调查结果一致.该模型可应用于建筑物结构类型分布与玉树县结古镇相似的城镇遥感震害评估工作中.
