摘要:
利用空间变异理论对堆积体边坡降雨引起变形的特点进行分析后,拟合出变异函数理论模型。因模型参数确定非常困难,利用遗传算法在求解非线性问题时具有全局寻优的特点,结合遗传算法拟合出变异函数理论模型参数。依据降雨时监测的小湾水电站左岸堆积体边坡的变形数据,进行降雨条件下的时间及空间变异性分析,得出边坡的变形特点。为能充分反映降雨引起堆积体边坡变形的空间方向变异性,构造出方向综合变异指标Ov,对其进行定量描述。最后通过实例验证了降雨条件下堆积体的时间及空间变异性分析及综合变异指标Ov理论的正确性。这种研究方法对堆积体边坡的相关研究提供了一种新的分析方法和思路。
Abstract:
The previous method uses the theory of spatial variation to analyze the deformation characteristic of the talus slope under the rainfall and then fit the theoretical model of variation function. But it is very difficult in this model to fit the parameters. the genetic algorithm is applied to fit the parameter of spherical model variation function, because the genetic algorithm have the advantage on seeking priorities in fully exert when use it to solves the nonlinear problems. Then analyzing temporal and spatial variability of talus slope under rainfall by combining with the data of the high talus slope on the left bank in Front of Xiaowan Hydro Plant Dam in Yunnan is employed to calculate and test as an example. And the deformation characteristic of talus slope under rainfall is obtained. Finally based on spatial analysis of regional variable parameters that the directional synthetic variance index Ov are present, then using this index quantitative description the directional variation of talus slope. The result demonstrates the accuracy of the theory of analysis to talus slope temporal and spatial variability under rainfall and direction variation index. It provides a new analytical method and ideas for the deformation research of talus slope.
