Other Abstract

 成昆铁路屡遭泥石流危害。铁路系统、路外科研单位、大专院校和地方政府对沿线的泥石进行了大量调查研究和防治工作,撰写了许多考察报告,发表了不少研究论文,取得了宝贵的经验,总结了深刻的教训。 为进一步探讨沿线泥石流的属性、活动状况和发展趋势,并据此作出综合防治规划和提出综合治理措施,1983年初中国科学院受四川省建设委员会的委托,根据国务院有关文件精神,指示我所组建成昆铁路北段泥石流及防治研究课题组,对占全线泥石流沟总数90%、受害最严重的成昆铁路北段(即四川境内)的泥石流进行全面系统的考察研究和深入的分析论证。

 

 

;  The railway line from Chengdu to Kunming is damaged very often by debris fliows. Since 1983,a new project of studying debris flows along Chengdu-Kunming Railway was carried outby Institute of Mountain Hazards and Environment,Chinese Academy of Sciences & Ministry of Water Conservancy. Three main results have been obtained by 1987.1. Monograph"Debris Flow Research and Prevention "(Sichuan Press of Science and Technology, 1989, p. 1-358) ;2. Colour map of debris flow activity along Chengdu-Kunming Railway (1:200000); 3. Data-base of debris flow gullies and their characteristics.The essentials of the monograph of debris flow research and prevention are:1.The criteria of distinguishing debris flow gullies are listed. There are 367 debris flow gullies along the railway determined according to the criteria.2.The main factors in debris flow formation have been analysed with IBM computer. The first place in debris flow formation occupies gradient of the basin and water supply,the second is rainfall and geological structure,and then is vegetation cover.3.The maximum impact force of debris flow bursting is calculated as 2100 t/m2.4.According to the principle of classification of debris flow (such as with the rules of scientific meanings,easy in practice and simple in understanding) ,7 different classes of debris flow are suggested.5.Based on the model of SD-system, the tendency is to be stronger and stronger for debris flow activities during 1990-2000 in this region.6.Some new methods and technics such as electronic-microscope,modeling in computer, method of systematic dynamics,new method of mapping and data-base of debris flow are adopted in the analysis and research work.7.The planning for debris flow comprehensive prevention has been mapped out. Engineering , vegetation and administrative measures for preventing and controlling debris flow have been designed.8.System of preestimate and forecast of debris flow is established. 18. 4 times of bursting each year are to be occurred in the period of last decade of this century.
