谈工程地质的学科价值与学科发展

工程地质是一门认知工程－地质相互作用规律和过程的科学，它的使命是保障人类工程活动的安全。工程地质学科的基本理论形态包括“成因演化论”、“结构控制论”和“相互作用论”，这些理论有着相通的思想方法，就是成因决定结构，结构控制行为，工程地质过程是工程建设与地质环境相互作用的过程。随着我国近期工程建设的规模增大，埋藏加深，地质条件更复杂，由此带来的工程地质问题表现出显著的新特点，即研究对象大、深、动、热凸现，工程地质过程水、岩、温、化耦合，已有理论遭遇挑战，工程地质过程研究需要扩充。工程地质学科近期需要加强地质体工程性质研究、工程地质动力过程研究，以及地质环境研究。地质、地球物理、力学、工程科学的结合是工程地质学科发展的有效途径，理论、技术方法与实践并重的模式是工程地质学科发展的基本模式。

ON PROFESSIONAL VALUE |AND DEVELOPMENT OF ENGINEERING GEOLOGY

The profession of engineering geology  provides knowledge and methods to cognize the regulation and course of the interaction between engineering and geology. Its task is to guarantee the safety of engineering activity of human beings.  Its essential  theories  include (a) geology of origination and evolution, (b) domination of geological structure, and (c) interaction between engineering and geology. These three theories have the similar thinking process that the origination determines the structure, the structure dominates the behaviors. Engineering geological process  is actually a process of interaction between engineering and geology. At present,  engineering projects have become larger and larger and deeper and deeper and their encountered geological conditions have become more and more complicated. Consequentlyengineering geological problems present new features and its objects  have become remarkably large, deep, dynamic and high temperature. Coupled actions among fluid, stress, temperature and chemistry  have challenged the exist theories that were developed for relatively simple ground conditions.  Research on engineering geological process should be further extended. Further combination among geology, geophysics, mechanics and engineering sciences is believed the most effective approach.  Paying equal attention to theory, technology and practice is the basic mode for the further development of engineering geology profession. 
