The construction process of the underground waterway tunnel was divided into two stages and the calculation and after treatment was carried out by using the ABAQUS element technique. The study on the ground stress in the working area and the stability of the surrounding rocks were analyzed to improve the reliability of the initial surface stress equilibrium method. As shown in the results, we can know the parameters of the surrounding rock material affect the development and deformation of the surrounding rocks during the construction of the underground waterway tunnel, and the different excavation processes also affect the deformation and the flow of the surrounding rocks.
