滑坡灾害超前预判技术研究

以地质构造控制论为理论核心,以地层、构造、地形等要素的系统分析为指导,以滑坡的形成、演化及特征为对象,首次提出了滑坡地质灾害超前地质预判的概念:滑坡灾害超前地质预判主要是指在各级勘察工作前期,不借助任何勘探手段,运用各种超前地质预判的方法,根据滑坡的地质地貌特征确定滑坡的空间位置及滑坡类型,预测其未来发展状况的一种技术方法。以此建立了该技术的基本体系、判别方法及工作程序,并在陕南公路沿线地质灾害调查过程中进行了初步应用。

TECHNIQUE FOR PRE-ESTIMATION GEOLOGICAL HAZARD OF LANDSLIDE

The authors in this paper,according to the system analysis of stratum,constitution and landform,through studying the formation,the development and the characteristics of landslide,put forward the conception of pre-estimating landslide firstly based on the geologic structure cybernetics.The pre-estimating system for landslide is a technical method,which can determine the space position and the type of landslide,and can pre-estimating its developmental condition in the future without any exploration means,but according to all kinds of geological pre-estimating methods and topographical features of landslide.The authors build the basic system,the discriminating method and the working procedure of this technical method.They have applied this method to investigating the geological disasters along highways in Southern Shaanxi.This method has noboth theoretical and practical meaning.
