Analysis of the geomorphological features of coral reef and computation with the mathematical model show that the raised zone of coral zone could serve to reduce wave energy and that about 80 % wave energy could be lost when it passes through the zone 通過對珊瑚礁地貌特征分析,運用數(shù)學(xué)模型進行運算,得出約有80的波能由于珊瑚礁突起帶的消浪作用而損耗。珊瑚礁突起帶對波浪的消減作用與水深、波要素有關(guān)。
In this pattern a new kind of infinite boundary element is developed to reduce wave reflection on the boundary . by this method , a simple and convenient numerical way is worked out and dissipation of the pore press , damping can be taken into account . it can not only solve the problem of material nonlinearity , but also be suitable for the problem of large deformation 考慮到反射波在計算區(qū)域內(nèi)經(jīng)多次反射、透射和散射對計算結(jié)果可能產(chǎn)生較大的影響,在上述飽和砂土有限元模型的基礎(chǔ)上,建立了一種新的動力無限元計算模型,該模型能滿足工程計算的要求。
Essential to their utility is the requirement that the evolution of the basic functions through the propagation environment constitutes a simplified problem with an exact or approximate closed form solution to the original wave equation . the evolution of a spatial fourier harmonic through a homogeneous medium is governed by a reduced wave equation , obtained by applying the fourier transform to the helmholtz equation , with a simple and well - known solution - the plane wave 這些方法均采用一組具有全局特性的基本函數(shù)對波場進行分解,如占據(jù)整個空間的富氏調(diào)諧函數(shù)或充滿各個方向的dirac函數(shù)(點源) ,并通過求解基本函數(shù)滿足波動方程的精確解或近似解來達到波場外推的目的。
