Groundwater Dynamic Method and Parameter Analysis of Tunnel Water Inflow

Abstract

The construction of tunnel engineering inevitably affects the water environment in the tunnel site area, and the most important reason is the tunnel water inflow caused by the tunnel engineering. The water inflow quantity of tunnel is an important parameter for the design and construction of high water level tunnel, which has been the focus of scholars' attention. Based on the research results in recent years, the commonly used groundwater dynamic methods for predicting tunnel water inflow are introduced, and the parameters in the theoretical formula are analyzed. The influence of the change of parameters on tunnel water inflow is discussed, which provides a reference for further understanding tunnel water inflow
