The study on retarded creep behavior using creep theory under condition of reservoir water lever in stabilized status for one and a half year demonstrates that the viscous coefficient of sliding soil shall increase as creep procedure continues , meanwhile , the displacement process of landslide surface area fitted by logarithmic curve matches closely with measured values 以蠕變理論研究在庫(kù)水位穩(wěn)定一年半的條件下滑坡的減速蠕變現(xiàn)象,證明滑帶土粘滯系數(shù)隨蠕滑過(guò)程不斷增大,以對(duì)數(shù)曲線擬合滑坡表部位移過(guò)程與實(shí)測(cè)值吻合較好。
