工程地质问题的影响因素多而复杂，兼有定性和定量指标，要精确地进行量化极其困难。数量化理论提供了将定性数据和定量数据进行量化进而建立预测评价模型的方法，为工程地质问题分析提供了便利。本文论述了数量化理论原理及其发展概况，综述了数量化理论在工程地质领域的应用现状，数量化理论在该领域的应用主要集中在影响因素的识别和提取、建立工程地质预测评价模型、地质因素的判别分析、相关性分析等方面。文章根据实际应用中遇到的问题分析了数量化理论的局限性：区域间的“迁移性”、评价的“后验性”以及指标选取的科学性，并针对性的提出两种处理方法：（1）对大量样本进行部分细致的工程评价，建立与评价对象符合的模型，利用模型进行快速评价；（2）根据大量不同类别样本建立的不同模型，实际应用时根据实际样本情况，选取针对性的计算模型对地质模型进行评价。最后，本文结合工程地质发展趋势，以及各种方法手段的引入介绍，论述了数量化理论在工程地质领域的应用前景。

Engineering geological problems are characterized by many influence factors including both qualitative and quantitative indicators.Therefore,quantitative evaluation of engineering geological problems is extremely difficult.The quantification theory guides to quantify the quantified and qualitative data,and to build the formula for prediction and evaluation.The quantification theory provides the convenience for the analysis of engineering geological problems.This paper summarizes the application of quantification theory to engineering geological analysis including recognition,prediction,coupling analysis and correlation analysis.Recognition refers to select significant geological features in numerous factors of the geological model,makes the evaluation of its importance. The prediction means to establish a model for similar samples calculated to evaluate its possible outcomes by using the data of existing factors and results of the evaluation.The discrimination of geological factors and correlation analysis of its consequent are the analysis of “positive and negative correlation”of the factors by inter-model affecting.According to the problems encountered in the practical application of quantification theory,the limitations of the theory is analyzed,which are “otherness”between the regions,“posteriori comparisons”of assessment and the scientificity of indicator selection.Two approaches to solve the problems are put forward:i)the model should be created based on geological survey for the site that match the model,ii)depending on the model created by a large number of different types of samples,such as lithology,combination of structural plane,discontinuities types,etc. When applying the geological model,specific computational model should be considered to evaluate the geological problems.At last,the suitability,the evaluation methodology and development trends of quantification theory are analyzed.
