Design of Hydrogeological Information Model for Rock Tunnel

Rock tunnel is a kind of large-scale infrastructure with long-term investment cycle and complex technologies, involving a number of participants. Aiming at a large number of hydrogeological data in the project, establishing a standard description of unified information and sharing mechanism can effectively solve the problem of serious data loss and low information utilization rate. At present, rock tunnels are lack of unified standards for hydrogeological data. This paper takes the Laoying tunnel of Yunnan Province as the background to design a rock tunnel hydrogeological information model. The purpose is to unify the storage and transmission of data and solve the problem of file format incompatibility between different softwares in tunnel engineering. In addition, this paper proposes a new groundwater table estimation method, which has higher accuracy than the traditional method of using borehole data to interpolate, and thus can further optimize the hydrogeological information model.
