济南隧道工程岩溶发育区勘察方法探讨

The Investigation Method for Karst Development Area of Ji'nan Tunnel Project

济南地区碳酸盐岩广泛发育,岩溶发育会对隧道工程施工和工程运营安全产生影响,为保证工程安全,岩溶勘察不可或缺。论文以济南某盾构隧道岩溶勘察为例,系统地介绍了勘察的方法和手段,并进行了科学的统计分析,对岩溶的发育条件、发育类型、发育程度、发育规模及稳定性进行了评价,有效地指导了设计与施工,保证了工程的顺利贯通。

The carbonate rocks are widely developed in Ji＇nan area. The development ofkarst has an impact on tunnel construction and operation safety. In order to ensure the safety of the project, karst investigation is indispensable. Taking the karst investigation of a shield tunnel in Ji＇nan as an example, this paper systematically introduces the methods and means of the investigation, and makes a scientific statistical analysis. It evaluates the karst development conditions, karst development types, development degree, development scale and karst stability, effectively guides the design and construction, and ensures the smooth progress of the project. The interest is through.
