Development of a Groundwater Forecasting System and Groundwater Flow Prediction Technology Using Digital Twin

Abstract

In recent years, with the development of IoT and ICT technologies, an environment has been created in which digital data related to construction can be easily obtained. This paper describes a basic system that combines such digital data and numerical simulation technology, based on the digital twin concept, to reproduce in a virtual space the "amount of water inflow into the face" and "results of geological survey during construction" obtained during mountain tunnel excavation. The basic system was constructed to numerically simulate the amount of water inflow that will occur in the near future by updating this information. The information predicted by this system could reduce geological risk by disseminating information in a timely manner and in a form that is easy for everyone to understand, thus contributing to safe and secure construction.
