西安市白鹿塬滑坡发生时间预测研究

Time prediction study on occurring of landslides in Bailuyuan, Xi’an

摘要: 笔者通过对白鹿塬区降水与滑坡发生时间之间的规律进行总结,认为本区滑坡发生与降水的丰年有着密切的关系,并应用卡尔曼滤波分析法对白鹿塬区滑坡发生时间进行了全区性预测,提出白鹿塬滑坡发生具有10年左右的中周期,20年左右的长周期,应及早作好防治工作。

Abstract: The author thinks that there is a very good relativity between occurring of landsides and rainfall in Bailuyuan area, according to the data of weather in Bailuyuan area and using Kerman sieve wave analysis method.It is conclusions that there are 5 years short cycle, 10 years middle cycle and 20 years long cycle in landslides of Bailuyuan area. Hence, the judgment that there is a concentrated occurring of landslides in 2003 is made. Meanwhile, the difference and regulation of rainfall in different neighbour area are discovered,and prediction of rainfall in Bailuyuan area can be made according to the rainfall information from Ninqiang county. Therefore,the preventive methods of land slides can be made ahead of time.
