本文在简要介绍燕山水库工程地质环境的基础上，分析论述了可能产生的环境工程地质问题。指出水库淹没及浸没、水库诱发地震、坝基渗透变形及膨胀土体稳定问题是该水库的主要环境工程地质问题，并提出了进一步研究的途径。 Based on the brief introduction of geological environment of Yanshan Reservoir, this paper analyzes and discusses the possible environmental engineering geological problems. It is pointed out that the inundation and submergence of the reservoir, the earthquake induced by the reservoir, the infiltration deformation of the dam foundation and the stability of the expansive soil are the major environmental engineering geological problems of the reservoir, and the ways of further research are put forward.
