| Abstract: | A new numerical simulating method for calculating open tunnel flow is established by using analytical function theory,the method for calculating the unknow discharge is put forward.The flow parameters such as discharge,free surface profile and boundary pressure distribution are simulated by numerical calculating the boundary integral equations.The calculating indicats that the method demonstrats good and fast convergence with small calculating quantity.The numerical results agree well with those meas ured. |
