Mountain Protection Forests against Natural Hazards and Risks: New French Developments by Integrating Forests in Risk Zoning

Forests can play a very significant role in protection against natural hazards and risks in mountain lands, especially against erosion and rockfalls. This paper first assesses knowledge concerning the capacity of forests to control natural hazards, with emphasis placed on forest location in catchments or slopes. Zoning aspects are then presented; based on the use of GIS, they allow determining priorities for forestry operations (cuts and biological engineering), in view to setting up an 'optimal management' of mountain forest ecosystems. Finally, an explanation is given of how the results of research are used for the management and planning of mountain ecosystems, illustrated by an example of researcher-practitioner transfer in France. Zoning, prevention, display and regular aspects are developed. On the basis of the experience and knowledge presented here, recommendations are proposed to better take into account the role of mountain forests in the control of natural hazards and risks. It is necessary to have an adapted legislative and economic framework, define priority forest intervention zones and determine an adapted sylviculture.     

Mitigation of liquefaction and associated ground deformations by stone columns

Soil liquefaction and associated ground failures have been a major source of damage during the past earthquakes. The risk of liquefaction and associated ground deformation can be reduced by various ground-improvement methods including the stone column (gravel drain) technique. This paper presents the current state of the stone column technologies as a liquefaction countermeasure. A comprehensive review is provided aiming to: (a) identify key considerations for the general use of stone columns as a liquefaction countermeasure, (b) provide insights for design and construction, (c) compile the latest research developments, and (d) identify sources of useful information. Case histories of field applications and observed field performance are cited to portray different stone column applications and observed effectiveness. The paper identifies areas where more research is needed and includes recommendations for future research and development.

2003年12月1日新疆昭苏6.1级地震烈度与房屋震害

介绍了2003年12月1日新疆昭苏6.1级地震的现场考察结果.该地震宏观震中位于受灾最重的兵团农四师76团11连西侧,极震区烈度为Ⅷ度;圈定出Ⅷ度、Ⅶ度和Ⅵ度3条等震线.此次考察还着重考察了震区各类典型建筑的受损特征,对受损原因作了初步分析,所取得的经验可供类似地区抗震设防和民房改造工作参考.     

刍议国际地震保险投保率

地震灾难带来的损失日益增加的问题，让保险业至今难以应对。地震发生频率低、损失巨大而保险公司的承保能力又十分有限，加之，社会公众的投保意识薄弱，造成地震保险投保率过低。从地震灾情入手，介绍了国际地震保险开展情况，剖析了地震保险投保率过低的原因，并针对问题提出了解决措施。
