摘要:
运动距离和速度是滑坡致灾区域和致灾强度的主要评价指标。颗粒级配、体积、斜坡坡度、下垫面摩擦系数、含水率等是影响这些参数的主要因素,按照正交试验原理设计模型试验研究这些因素对滑坡运动参数的影响特征。在试验基础上,采用极差和方差分析等手段,以滑坡的最大运动距离、最大运动速度为评价指标,对影响滑坡运动参数的5种因素进行了分析。结果表明:影响滑坡最大运动距离的诸因素中,斜坡坡度是最主要的因素,以下依次为下垫面摩擦系数、滑坡体积、颗粒级配、含水率,其中,斜坡坡度、下垫面摩擦系数和体积是影响最大运动距离的决定性因素;在滑坡最大运动速度的影响因素中,斜坡坡度也是最主要影响因素,以下依次为下垫面摩擦系数、含水率、颗粒级配和体积,其中,仅斜坡坡度是影响滑坡最大运动速度的决定性因素,其他因素的影响不显著。由此表明滑坡的运动距离是滑坡体规模与运动场地条件耦合作用的结果,而最大运动速度受控于斜坡坡度。
Abstract:
Model test of landslide movement was designed in terms of the design theory of orthogonal test, of which 5 influential were considered including grain composition, volume, gradient of slope, friction of underlying surface, moisture content. And these 5 influential factors were analyzed with the experiment by means of range and variance. During the analysis, the evaluation criteria were the maximum movement distance of landslide and the maximum speed. It is shown that among so many influential factors of the maximum movement distance, the gradient of slope is the most important one, followed by the friction of underlying surface, volume, grain composition, moisture content, in turn. The gradient of slope, friction of underlying surface and volume are critical factors for the maximum movement distance. It is also shown that among so many influential factors of the speed the gradient of slope is the most important one, followed by the friction of underlying surface, moisture content, grain composition and volume. Among 5 influential factors, only the gradient of slope play an important role of the maximum speed and other factors are not significant. The results indicated that movement distances of landslides are coupling of the volumes and movement ground and the slope gradients control the maximum speed.
