岩溶塌陷综合预测评价的理论与方法

COMPREHENSIVE EVALUATION AND PREDICTION OF KARST COLLAPSE: THEORY AND METHOD

本文结合岩溶塌陷综合预测评价系统,对岩溶塌陷定量预测评价的基本思路和途径作了系统介绍,同时,针对土层性质、土层结构、基岩岩溶化特征、地下水特征、人类活动强度以及新构造活动等塌陷影响因素,分析了它们在塌陷形成过程中的作用,提出了这些具有不同来源空间数据资料的分析、处理并生成相应数字图象的方法,最后,详细叙述了预测评价模型的建模技术,并以实例说明这一方法的可靠性和实用性。

It is a paper about the 'Comprehensive Evaluation and Prediction System of Karst Collapse' developed by the Institute of Karst Geology. Firstly, the approach of collapse evaluation is discussed in detail. Secondly, according to the collapse mechanism, the influence factors, such as soil properties, soil structure, bedrock karstification, groundwater condition, human activities etc. , were analyzed. Additionally, it is showed the method to convert these data with different sources to digital images. Thirdly, it is discussed the way to establish a quantitative model for collapse evaluation. Finally, a case study result is presented.
