Process of Housing Damage Assessment: The 1995 Hanshin-Awaji Earthquake Disaster Case

Rebuilding of victims' livelihoods was a crucial issue in the restoration process in the1995 Hanshin-Awaji Earthquake Disaster. Housing damage assessment influencedmost of the rebuilding of the livelihood in the long term, because the Victim Certificatesissued by the local governments based on the results of the Housing damage assessmentwas required to receive most of the individual assistance measures. In the process ofHousing damage assessment, many complex problems arose, leading to extensivework on the part of the disaster responders. Consequently, a considerable number ofvictims were dissatisfied with the assessment and applied for a resurvey. Due to a floodof requests for resurvey, disaster responders had to work on damage assessment, leavingrelief activities aside.In order to facilitate Housing damage assessment, this paper discusses thefollowing five points: (1) the processes and the problems of assessments performedin the Hanshin-Awaji Earthquake Disaster, (2) the changes in the nature of informationneeded by the victims, (3) the improvements over the present damage assessment, (4)the housing situation in Japan, and (5) the international situation on damage assessment.It is obvious from the results that a poor damage assessment system and the size ofthe disaster produced a very large work load. Differences in appreciation among theinvestigators also contributed to unfair assessments and led to the victims beingincreasingly dissatisfied by the survey results. Finally, a design concept for acomprehensive damage assessment system, which has been derived from theabove five points, is proposed for post-disaster management.     

泥河湾地区晚新生代生物地层带

本文根据岩石地层，哺乳动物化石及古地磁资料的综合分析研究，将泥河湾地区晚新生代生物地层划分为５个生物地层时限带，并推算出每个带的年限，它们是：（１）Ｈｉｐｐａｒｉｏｎ ｈｏｕｆｅｎｅｎｓｅ时限带，？－３．３０Ｍａ；（２）Ｍｉｍｏｍｙｓ ｏｒｉｅｎｔａｌｉｓ时限带，３．３０－２．４８Ｍａ；（３）Ｍｉｍｏｍｙｓ ｙｏｕｈｅｎｉｃｕｓ时限带，２．４８－１．８７Ｍａ；（４）Ａｌｌｏｐｈａｉｎｏｙｓ ｃｆ．     

山东烟台南部海岸带地区土壤重金属来源、空间分布及潜在风险评价

海岸带处于陆地和海洋的接合部,人类开发活动密集,环境影响因素日趋复杂。选取烟台南部海岸带为研究对象,系统采集686个表层土壤样品对As,Cd,Cr,Cu,Hg,Ni,Pb,Zn共8个重金属元素含量进行测量,采用多元统计法及地统计法分析了8个重金属元素的来源及分布特征。最后对烟台南部海岸带地区进行了潜在生态风险评价。研究结果表明烟台南部海岸带地区整体污染程度较轻,所有重金属元素含量平均值均未超过国家二级标准。其中Cr,Ni,Cu元素主要来源于成土母质;As,Pb为混合源;Cd,Zn主要来自于工业三废、农业生产。研究区整体处于中低生态风险水平,Cd,Hg元素高生态风险点数量较多,需优先治理。     

Palaeogene Biostratigraphic Characteristics of Red Basins In Western Henan and Its Adjacent Areas, With an Outline of Palaeogene Palaeobiogeographic Provinces of China

This article is a preliminary summary of Paleogene biostratigraphy of the Liguanqiao, Tantou andYuanqu basins, with a new proposal for Paleogene paleobiogeographic provinces of China. On the basis of asynthetic analysis of the geological data, characters of the mammalian assemblages and their comparisons withother corresponding faunas, a new scheme on Paleogene biostratigraphic subdivision of the basins has been putforward here. Based on differences of biostratigraphic sequences, characteristics of mammalian assemblagesand directions of faults controlling Paleogene basins in China, six Paleogene paleobiogeographic provinces ofChina have been proposed in this paper, that is: Tianshan-Yinshan-Tumen Province; Tarim-North China Prov-ince; Kunlun-Qinling Province, Yangtze Province, Nanling and Southeastern Coastal Province, Qinghai andTibet Province.

基于SVG的高速公路横断面交互式可视化研究

高速公路建成后,养护、管理或改建时快速查看横断面结构、构造物等信息是十分重要的。本文以伊辽高速为例,通过数据提取、处理,实时生成高速公路横断面数据;并通过数据解析,使横断面数据成为SVG绘图的数据源,进而实现了Web下交互式横断面的绘制,从而直观地展现了道路、路基、道路附属设施、道路构造物等信息,便于高速公路管理和养护决策。     

合成的台湾M_S8.0级大震在上海产生的地震动

2015年4月25日尼泊尔发生了M_S8.1级地震,给人们的提示是:在发生过强震的地方,有可能再次发生同样强度的地震。自上世纪20年代以来,台湾就发生过两次M_S8.0级大地震,遗憾的是对两次强震均未获得强震加速度记录。上海是目前世界上高层建筑最多的城市。本文用经验格林函数法合成台湾M_S8.0级大地震,通过合成得到加速度时程来估算对上海产生的地表面波强度。将来台湾一旦发生M_S8.0级大地震,其面波对上海高层建筑的影响也将最为显著,本文给出的估算强度旨在为地震应对和应急救援提供一定的参考。
