项目摘要

Global concern about the environment and sustainable development reaches a new peak in the 21st century. In order to establish reliable landslide risk evaliation and hazard assessment for planning prevention work before landslide disaster occurrence, UNESCO-IUGS IGCP-425 started international joint research and obtained following results.1.New precise displacement sensors using electro-magnetic pulse were installed at extensometers in Lishan landslide slope, Xian, China. Data logger for automatic monitoring and long-distance data transfer system are installed and tested.2.New extensometers and crack gauges using differential-transducer were developed and installed in 2000-2001 in a rock slope of Bitchu Matsuyama Castle, Okayama Prefecture, showing obvious instability. They showed deformation of the slope on the order of a few mm in 3 months at maximum.3.IGCP-425 general meeting was organized at UNESCO, Paris, in September 1999 and discussed about cultural heritages at landslide risk of the world and landslide hazard assessment/mitigation.4.Preliminary investigation was conducted at the most well-known UNESCO world Heritage "Machu Picchu" Inca ruin in Peru, which is located on the head scarp of large-scale rock slide, in November 2000 in cooperation with INC, INRENA, IGP etc. Ten sets of simplified extensometers and 2 sets of pen-recording type were installed for preliminary monitoring of the slope deformation in November 2000.5.UNESCO/IGCP Symposium on Landslide Risk Mitigation and Protection of Cultural and Natural Heritage was organized in 15-19 January 2001 at Science Council of Japan in Tokyo. Sassa reported the preliminary investigation in Machu Picchu and monitoring system in Lishan landslide.

21世纪，全球对环境和可持续发展的关注达到了一个新的高峰。为了在滑坡灾害发生前为规划预防工作建立可靠的滑坡风险评估和危害评估，UNESCO-IUGS IGCP-425开展了国际联合研究，获得了以下结果：利用电磁脉冲技术在西安骊山滑坡延伸仪上安装了新型精密位移传感器。安装并测试了用于自动监控的数据记录仪和远程数据传输系统。2000-2001年，在冈山县碧初松山城岩质边坡上安装了新型的位移计和裂纹计。结果表明，在3个月内，边坡的最大变形量为几毫米。4. 1999年9月在巴黎教科文组织举办了IGCP-425大会，讨论了世界面临滑坡危险的文化遗产和滑坡灾害评估/减灾问题。2000年11月，与INC、INRENA、IGP等合作，对位于大型岩滑梯头陡处的秘鲁最著名的联合国教科文组织世界遗产“马丘比丘”印加遗址进行了初步调查。2000年11月，安装了10套简化伸缩仪和2套笔式记录仪对边坡变形进行初步监测。2001年1月15日至19日在东京的日本科学理事会举办了教科文组织/IGCP关于减轻滑坡风险和保护文化和自然遗产的专题讨论会。萨萨报告了马丘比丘滑坡的初步调查和骊山滑坡的监测系统。
