摘　　要：利用三维地质模型辅助分析水库区淹没、塌岸等环境地质问题,具有高效率与高精度的特点。以尖岗水库为例,基于CATIA软件平台,构建了三面临库的凤凰岛库区三维地质模型,该模型给出了各库水位工况淹没范围、淹没线等,并在此基础上对塌岸宽度进行了预测分析。工程运用实例表明,采用上述方法可大大提高对此类问题的计算效率与工作精度,为水库环境地质问题分析评价开辟了新思路。CATIA software was used to build a three - dimensional geological model for the Phoenix Island surrounded by water area of Jian＇ gang Reservoir. The model can calculate the submerged area and submerged line under various water level of Jian＇ gang Reservoir quickly and accurately. Furthermore, the width of bank collapse zone was predicted. The model improved computational efficiency and accuracy greatly, which creates a new way for the evaluation of environmental geological problem of reservoirs.
