The measurement of tunnel water inflow is not only an important basis for engineering design changes, but also an effective verification of design. This paper combines with the analysis of the measured data of groundwater of large water inflow section, which appeared in the construction of high-speed Jianfeng mountain super long tunnel in Fuling Fengdu, Chongqing city, and detailed information of hydrological survey results. This paper has re-evaluated the engineering geology and hydro-geological of large gushing sections to clear the reason of water inflow, the development trend characteristics of groundwater and stability of surrounding rock. It is shown in this paper that the measures such as strengthening the support parameters, optimizing the waterproof and drainaging design schemes, and other measures can be adopted to ensure the safety of tunnel construction and effectively realize the concept of dynamic construction.
