摘要

Study the accurate warning of landslides. The paper put forward a data mining algorithm based on formation pressure landslide warning methods. Through the formation pressure variable relationship, formation pressure variables related parameters wwere calculated, and through the formation pressure data mining method, the landslides hazard warning was given. The experimental results show that this algorithm can effectively improve the accuracy of the landslide warning.%研究山体滑坡的准确预警问题.山体滑坡形成过程极为复杂,发生时间较短,山体不同区域承压也有较大差别,各地区压力动态关联性不一致.传统的预测手段多是基于小区域,压力集中的条件下进行预测,一旦各地区承压关联出现混乱,会导致传统的单一山体承压模型反应滞后、甚至错误,造成挖掘不准.为了避免上述缺陷,提出了一种地层压力数据挖掘算法的山体滑坡预警方法.通过地层压力变量关系,计算地层压力变量相关参数,通过地层压力数据挖掘方法,对山体滑坡灾害进行预警.实验结果表明,提出的算法能够有效提高山体滑坡预警的准确性.
