摘　　要：将三维建模应用于工程地质中表达地层环境,通过数字化方式为工程地质相关评价提供重要依据。分别利用处于不同地形下两项工程的钻孔和地质数据等资料,综合绘制工程地层剖面并构建三维地层模型,通过结合虚拟钻孔、专家经验等方式优化模型,使独立、不均匀的钻孔数据以三维可视化的方式将地层结构等信息具体形象表达。还原了地层沉积分布情况及内部细节,可辅助分析不同场地的工程地质特征,提出经济合理的地基处理方式,并在后续基坑开挖和桩基施工时验证地层模型表达符合现实地层分布。3D modeling is applied to express the stratigraphic environment in engineering geology.And through digitalization,it provides an important basis for engineering geology evaluation.Boreholes and geological data of two projects in different terrains are used to draw engineering stratigraphic section and construct 3D stratigraphic model.The model,combined with virtual drilling and expert experience,the independent and uneven borehole data can express the stratum structure and other information in a 3D visualization way.The distribution and internal details of stratum deposition are restored,which can be used to analyze the engineering geological characteristics of different sites and propose economic and reasonable foundation treatment methods.The stratigraphic model is verified to be consistent with the real stratum distribution during the excavation of the post-sequence foundation pit and pile foundation construction.
