摘要:

针对城市地铁沿线地质条件变化较大、现场勘察难度较大的特点,引入地质3D数字建模技术,进行城市地铁沿线地质条件分析方法的探讨。以北京市在建地铁8号线二期南段为例,进行地质3D数字建模技术的应用,应用结果表明在城市地铁跨越多个地貌单元条件下,所提出的分析方法能够较全面地分析复杂的地质规律,进行合理的地层条件统一划分。为地质条件复杂的北京地铁8号线二期南段施工设计提供了便捷的参考依据,同时也为一般性的城市地铁沿线地质条件分析工作提供了一种弥补性方法层面的探讨。

Abstract:

The geological conditions along urban Metro lines vary dramatically and it is difficult to perform site investigations on the geological conditions along urban Metro lines. In the paper, the analysis of the geological conditions along urban Metro lines by means of 3D geological digital modeling technology is discussed. The technology mentioned is used in the analysis of the geological conditions of the southern part of Phase II Project of Line 8 of Beijing Metro. The application shows that the rules of the geological conditions along Metro lines can be well analyzed by means of the technology described, especially when they cross multiple geomorphic units. The paper can provide reference for the design and construction of the southern part of Phase II Project of Line 8 of Beijing Metro and also can provide reference for the analysis of the geological conditions along other urban Metro lines in the future.

Key words: urban Metro, geological condition, 3D geological digital modeling technology
