1995年康定城区洪灾成因分析

分析洪灾成因 :长时间连续降雨和随后而至的暴雨 ,是山洪成灾主要因素 ;特殊的水系结构使洪峰流量在城区河流汇合处叠加 ;山洪的动能大 ,挟带泥沙和冲蚀能力强 ;泥石流、滑坡、崩塌强烈活动 ,为山洪提供大量泥沙、推移质 ;人类经济活动不当 ,加大了灾害损失     

水灾遥感实时监测与快速评估的实践与思考

总结了参加１９９１￣１９９５年间３次水灾遥感监测与评估科学实验所取得的结果，并结合国情分析，提出进一步发挥航天遥感作用，航天与航空相结合，建立一个花费较少，切实可行，能满足水灾实时监测与快速评估需要的设想。     

锚喷材料经时蠕变损伤本构方程

从以应力，湿度，温度和损伤诸函数的时间积分表示和自由能涵函出发，根据非平衡热力学定律，同时考虑了喷射混凝土老化效应及骨料因素，给出了锚喷材料损伤蠕变本构方程和损伤演化方程，养护时间及蠕变有效作用应力的定义，并用实验结果验证了该理论。

March 1990 Hailstorm Damage in Sydney,Australia

On 18 March 1990, an intense hailstorm in Sydney, New South Wales, Australia caused insured damage valued at A$million – the third most expensive loss event in Australian insurance history.While damage was widespread with claims for buildings spread across more than 130 postcodes, 20% of the claims came from just two postcodes. The proportion of dwellings of brick construction that made a claim was significantly less than the proportion of policies for this type of construction. Fibro (fibre-cement), timber and aluminium-clad dwellings are more likely to sustain damage than brick buildings in this type of storm.Hail caused the majority of damage to exterior building items while water damage more commonly affected interior building items and contents. While the repair of Interior building items such as ceilings and walls cost more than contents damage on average, the repair/replacement costs of contents contributed more to the total costs. Damage to window glass and roofs together made up more than 50% of the total claim.     

大型水域水岩相互作用及其环境效应研究

以大量实际资料及深入的研究成果，较全面地论述了人工大型水域水岩相作用及其导致的主要地质灾害，包括水库诱发地震，库岸崩滑，水岩作用导致的大坝溃决，以及水库淤积导致的大面积环境恶化等问题。     

2003年5月4日新疆伽师-岳普湖5.8级地震烈度分布及建筑物结构破坏特点

新疆伽师-岳普湖5．8级地震宏观震中位于岳普湖县的铁热木乡和兵团农三师42团的北面，震中烈度为Ⅶ度。本次地震影响范围位于巴楚-伽师6．8级地震Ⅵ-Ⅶ度影响区域内，累计破坏效应造成了较为严重的房屋破坏。通过对大量震害资料和强震记录的分析，根据建筑物的破坏情况和场地峰值加速度衰减特征，在尽可能排除累计破坏效应的基础上确定了地震烈度分布，分析了不同烈度区中的建筑物结构破坏特点及其与地震动影响场的关系。

遥感图象自动识别城市震害房屋-以2001年印度库奇地震和1976年唐山地震为例

近断层地震动对地表结构物造成严重的破坏，它具有明显的方向性和脉冲型特征. 在速度时程中含有大幅值、长周期的脉冲波，对结构响应影响很大. 为简化计算和分析的需要，在既有的等效速度脉冲模型的基础上，建议了较为合理等效速度脉冲模型. 在充分收集脉冲型近断层地震记录的基础上，对等效速度脉冲模型的脉冲周期、脉冲强度及卓越脉冲数等参数进行了研究，并与以往研究者的结果进行比较，以利于近断层区结构的抗震设计.      

The GIS and analysis of earthquake damage distribution of the 1303 Hongtong M=8 earthquake

The geography information system of the 1303 Hongton M=8 earthquake has been established. Using the spatial analysis function of GIS, the spatial distribution characteristics of damage and isoseismal of the earthquake are studies. By comparing with the standard earthquake intensity attenuation relationship, the abnormal damage distribution of the earthquake is found, so the relationship of the abnormal distribution with tectonics, site condition and basin are analyzed. In this paper, the influence on the ground motion generated by earthquake source and the underground structures near source also are studied. The influence on seismic zonation, anti-earthquake design, earthquake prediction and earthquake emergency responding produced by the abnormal density distribution are discussed. Foundation item: National important fundamental research “The Basic Research of Important Project in Damage Environment” and The important project “The Seismic Hazard Assessment Research and Anti-earthquake Structure Research” from China Earthquake Administration during the 10th Five-year Plan.
