双重介质属性滑坡预测模型分析

Analysis of landslip prediction model of slope with attribution of double-phase medium

滑坡是中国山区经常发生的地质灾害之一,往往会造成重大伤亡和损失.在考虑滑坡结构内部不同部位、不同介质属性介质的变形速率对变形量和总变形速率的不同贡献的基础上进行双重结构(介质属性)的滑坡预测模型研究,并对其解的存在性进行分析,论证模型存在预测解的充要条件,指出当模型具备解的存在性和唯一性时,只有存在非平凡解,进行滑坡预测才具有可行性.

Landslide is one of frequent geological disaster in mountainous area of China,which may often cause heavy casualties and losses.A landslip prediction model of double structure（medium attribution） was investigated on the basis of considering the contribution of the deformation rate different media with different attribution at different position in the landslip structure to the deformation amount and overall deformation rate.The existence of solutions of the model was also analyzed and the sufficient and necessary conditions of the existence of the solution were proved.It was pointed out that only when the solution of the model was unique and exists and has the nontribial solution,the performance of landslip prediction would befeasible.
