滑坡预报参数的选择和预报标准的确定方法

SELECTION OF PARAMETERS AND METHOD TO DETERMINE FORECASTING STANDARDS FOR LANDSLIDE

滑坡预报参数应选择速度变化率、声发射参数和降雨量参数。滑坡发展阶段不同,选择的动态参数也不同。滑坡发生的早期(或者滑坡处于圃结阶段)应以声发射参数为主;滑坡发展到滑动阶段应以速度变化率为主。滑坡位移动态类型可归纳为四类,每类有其典型的动态曲线,因此应根据滑坡动态曲线的类型建立相应的动态预报公式。

Prediction of landslides can be divided into two types, space prediction and time prediction. From various data collecting and monitoring systems of landslides, the dynamic characteristics of landslide can be obtained.How to use these dynamic characteristics to determine standards for landslide forecasts is an important problem.Different ways to determine different standards for forecasts of landslides are proposed according to different types of landslides, setting up a model based on the dynamic characteristics of different types of landslides is the basis of setting up forecast standards for landslides.
