摘　　要：地质环境是地质工程研究的一个重要内容,它直接关系着人类工程活动的成败与否,也直接影响着工程竣工后运营期间工程本身与地质环境的相互关系。特别是在进行工程活动场地稳定性评价时,地质环境因素是一个极其重要的因素,它包括地质结构(软弱夹层、软弱结构面等)、活动断层、地应力、地下水、地表水等方面。本文通过分析金川边坡变形失稳的原因,指出控制边坡变形的因素主要是高地应力、软弱夹层和地表水三方面,系统地说明了地质环境因素在工程活动中的作用。Geological environment is an important factor to be researched in geological engineering. It not only relates to the successes or not of engineering actives by human,but also makes influences on the relation between geological environment and engineering itself in the period of use after completion of construction. Especially when the evaluation is made for the stability of engineering site,the geological environment factors are very important.The geological environment factors include geological structure （soft intercalated bed and soft structural plane）, living crustal stress, ground water and surface water.On the basis of analysis of the causes for distortion and instability of Jinchuan side slope,this paper puts forward main factors for control of side slope distortion,namely high crustal stress,soft intercalated plane and surface water,and describes the role of geological environment factors in engineering actives.
