摘要
针对小东江滑坡体各测点的顺坡向水平位移以及垂直位移进行了建模分析,得出了位移与库水位、降雨量、及时效之间存在的相关性。系列数据显示目前滑坡体依然不稳定,影响滑坡体位移主要因素是时效,根据位移速率可以进行位移预测预报。降雨量可促使滑坡体加速下滑,而库水位对滑坡体的影响则是有限的。位移值大小存在明显的分区特征,因此局部块体失稳将是小东江滑坡体的主要破坏形式。
Aiming at the deformation of Xiaodongjiang creep landslide, a regression modeling is presented in this paper and the relativity among the displacement, water level of reservoir, rainfall and aging is described.A series of data show that the landslide is still instability at present and aging is the main factor that affects deformation. Since the displacement can be predicted by the displacement velocity and rainfall can accelerate the sliding process of Xiaodongjiang creep landslide while effect of water level of reservoir upon the landslide is limited and the feature of displacement value is fractal, part block losing stabilization will be the primary destroy form of creep landslide.
