The study of the influence of flow velocity on the internal force of deep arch ring

In the current code only have the calculation method of water pressure about pier, water pressure value of the main girder did not mention. Water and air belong to the fluid system, its motion and the stress are basically the same, so this paper quoted the calculation method of static wind load for the calculation of arch under water pressure, and the use of finite element software to analyze engineering examples, study the influence degree on the internal force of deep arch ring because the action of water pressure under the different flow velocity.
