Wave loading is an important environmental load of hydraulic structures for analysis of wave loads of high academic significance and practical value. In this paper, the numerical simulation method to calculate the hydraulic structures design wave front element , and then analyzes the force of waves on hydraulic structures , hydraulic structures made ??reasonable wave load analysis . First, in the traditional elliptic mild slope equation, the introduction of bottom slope interaction term , the energy dissipation and the nonlinear term , expanding the use of mild slope equation to improve the calculation accuracy , taking into account the deformation of wave refraction, diffraction , reflection , bottom slope , crushing , nonlinear , and many other factors , and the use of multiple experiments terrain slope equation for this model was validated numerical results agree well with the measured data . Secondly , the use of equations and boundary conditions of finite difference scheme established banded matrix equation , and using banded matrix solution with saving function Gaussian elimination (GEP France ) on the PC directly solve the elliptic mild slope equation , the calculation speed greatly improved , on the use of common methods for solving elliptic mild slope equation exists large computation to solve the problem of slow speed has been significantly improved . Finally, practical engineering , the use of numerical simulation method of direct calculation of hydraulic structures design wave front element and thus analyze the wave of small diameter piles building force , discusses the current specification does not specify Permeable Buildings the horizontal and vertical wave force calculation problem, a reasonable hydraulic structures wave load analysis .
