边坡稳定性类比评价的定量实现
QUANTIVATIVE ANALOGUE EVALUATION OF SLOPE STABILITY
-
摘要: 岩土边坡是一个受多因素影响、随时空变异的动态系统 ,它具有数据有限、不确定和没有原型等特点 ,因此 ,已有成功经验知识的运用在边坡稳定性评价中具有重要的意义。本文基于类比推理和灰色系统理论 ,提出了一种定量开发利用经验知识的新方法 ,并将其成功地应用于边坡稳定性分析和评价。结果表明 ,在运用经验知识方面 ,该法与目前广泛使用的神经网络方法有异曲同工之妙。此外 ,本文所提出的方法还具有简单、方便和实用等许多优点。Abstract: Slope is dynamic system affected by many factors and varies with time and in space. It is charactertized by limited data, instability, and without prototype, etc. Thus, use of the existing experience and knowledge is very important in slope stability analysis. A new approach to slope stability analysis and evaluation, using the existing knowledge, is presented in this paper based on the gray system and analogue. It has been shown from examples that the method provided here is simple and practical.
