城市地下管廊地质模型的三维化建立

Three-dimensional Establishment of Geological Model of Urban Underground Pipe Gallery

城市地下管廊所处的地质空间对于管廊全过程建设有重要的影响作用,尤其是在地质勘查阶段,因此管廊地质数据模型的研究十分必要。为了有效地展示综合管廊地质空间的现场状况和工程信息,本文以南宁市地下综合管廊建设项目为例,通过分析管廊地层状况,进行了三维多层DEM建模和地质划分,研究出了地下管廊地质模型的三维化建立,为管廊建设前期的勘察目的提供了科学参考依据。

The geological space where the urban underground pipe gallery is located has an important influence on the whole process of the pipe gallery construction,especially in the geological exploration stage.Therefore,the study of the geological data model of the pipe gallery is very necessary.In order to effectively display the on-site condition and engineering information of the integrated geological space of the pipe gallery,this paper takes the Nanning underground comprehensive pipe gallery construction project as an example.Through the analysis of the condition of the pipe gallery stratum,the three-dimensional multi-layer DEM modeling and geological division are carried out.The three-dimensional establishment of the underground pipe gallery geological model provides a scientific reference for the exploration purpose of the pipe gallery construction.
