在前人研究成果与实地调查研究的基础上，对黄河中游河口镇-龙门口地区水土流失、土地沙漠化、崩塌、滑坡、泥石流及地面塌陷等地质灾害类型、特征、灾情、发展趋势进行了剖析，并根据环境现状，提出了治理灾害策略．     

森林地表火蔓延边界预测预报图形显示系统

地表火蔓延状况的预测预报是森林防火灭火工作中的一项重要技术。目前，国外在预测火场扩展边界的形状及分布时采用了火场椭圆面假设，当可燃物、地形或气象条件复杂变化时，预测结果偏差较大。本文从地表火蔓延的本质入手，建立起确定复杂地形、气象条件和可燃物分布情形下的火蔓延边界的数学模型，并借助于现代软件编制技术，成功地编制出预测预报地表火蔓延边界的图形显示系统，率先实现了对任意情形下火蔓延边界的合理、准确的估算。

临沂市的岩溶塌陷灾害及防治对策

1995年前后，山东省临沂地区郊棉纺织厂等单位相继出现地面塌陷现象，同时穿过市区一条河流的水田桥附近河水下漏。在初步断定 这些现象由岩溶塌陷引起的前提下，采用了浅层地震勘探、地质雷达探测等技术，有选择地对临沂市西郊五个重点企业进行了岩溶调查。结果表明，在临沂市郊的浅层地表普遍发育着岩溶。岩溶的类型多样，岩溶的主要特征是埋深层，空间尺度小，密度大，从地下水抽取试验看，岩溶贯通性好。针对岩溶自身的特征以及临沂市的水文地质条件和环境，提出了减少或避免塌陷灾害的对策。主要是场地稳定性分析和评价，控制抽取岩溶水以及混凝土泥浆灌注，铺设桁架和清、爆、挖、填处理或者回避等。     

火灾下工程结构连续性倒塌分析与设计方法探讨

给出了火灾下工程结构连续性倒塌的定义,分析了工程结构在火灾作用下的特点,并给出了火灾连续性倒塌判断流程。在介绍目前常用的工程结构抗连续性倒塌分析设计方法的基础上,提出了采用替代路径法中的非线性静力分析方法对建筑结构进行火灾作用下抗连续性倒塌设计的思路。     

Search and rescue in collapsed structures: engineering and social science aspects

This paper discusses the social science and engineering dimensions of search and rescue (SAR) in collapsed buildings. First, existing information is presented on factors that influence the behaviour of trapped victims, particularly human, physical, socioeconomic and circumstantial factors. Trapped victims are most often discussed in the context of structural collapse and injuries sustained. Most studies in this area focus on earthquakes as the type of disaster that produces the most extensive structural damage. Second, information is set out on the engineering aspects of urban search and rescue (USAR) in the United States, including the role of structural engineers in USAR operations, training and certification of structural specialists, and safety and general procedures. The use of computational simulation to link the engineering and social science aspects of USAR is discussed. This could supplement training of local SAR groups and USAR teams, allowing them to understand better the collapse process and how voids form in a rubble pile. A preliminary simulation tool developed for this purpose is described.     

常州市老城区水体有机污染分布特征及原因初探

为了老城区河道的合理整治,采用总有机碳（TOC）分析仪对常州市老城区3条河流及区域内浅层地下水的14个采样点水样进行3个月的总有机碳含量检测。老城区水环境受到不同程度的有机污染,某些地下水的TOC含量高于地表水,原因为地表水补给地下水,且老城区水体污染源主要来源于周边地区的生活污水,并受到关河、雨水等的影响,这为常州市老城区水污染治理提供了依据。     

对地下水评价方法的探讨

ＧＢ／Ｔ１４８４８—９３《地下水质量标准》中推荐了一种评价地下水的方法,在实际应用时发现有如综合评价分值（Ｆ值）在水质分级时不连续等问题。本文对此,在单项组分评价分值Ｆｉ的计算及地下水质量级别的划分等方面提出了新的方法,不仅完善了该地下水的评价方法,并使该方法对于地面水的评价也有一定的参考价值。     

Advanced rescue techniques: lessons learned from the collapse of a building in Nairobi, Kenya

This paper examines the collapse of a five-storey building in Nairobi, Kenya, on 23 January 2006. It draws on reports from local authorities and on debriefings by Israel's Home Front Command (HFC), including information on injury distribution, rescue techniques, and the mode of operation. Most of the 117 people found under the structure were evacuated on the first day to a public hospital, which was overwhelmed by the incident. HFC forces arrived 23 hours after the disaster. At that stage, two people were still buried under the building and special techniques (tunnelling and scalping) were required to secure their evacuation. The two people quickly recovered after a short stay in hospital. Local technology is the preferred option during such events because time is crucial. International cooperation is required when this technology is not available. All of the hospitals in the disaster area, including private facilities, should participate in treating casualties.
