This study develops a rapid method for assessing the acoustic transmission properties of fluid-filled pipes under practical conditions involving an external medium. Initially, coupled equations for the fluid-filled pipe and the surrounding medium are established. Based on the dispersion characteristics, the influence of different external media on the propagation of the s = 1 wave mode is analyzed. Overall, the surrounding medium affects both wave speed and transmission loss within the pipe. Specifically, the added damping introduced by the external medium increases acoustic transmission loss. When the external medium exerts an axial force on the pipe, its axial natural frequency increases (by about a factor of 100 when embedded in soil compared to water), thereby suppressing resonant peaks in the transmission loss. The loading effect of the external medium also alters wave speed. When the pipe is embedded in soil, the low-frequency wave speed increases notably. A transfer matrix describing the relationship between variables at both ends of the pipe is derived using fluid pressure and displacement and pipe force and displacement. This model accounts for the external elastic medium, a feature frequently neglected in prior studies, to provide a more accurate representation of practical scenarios such as buried and subsea pipelines. Based on this matrix, a method for calculating transmission loss is developed, substantially reducing the time required to solve complex partial differential equations. The computed transmission loss aligns well with simulation data, validating the proposed method.

By applying the complex conjugate condition to the N-soliton solutions, the breather solutions are gained. Breathers can be transformed into nonlinear waves, which is known as state transition. By controlling the wave number ratio, five types of transformed waves are studied, including quasi-soliton, W-typed quasi-periodic wave, M-typed soliton, oscillation M-shaped soliton and multi-peak soliton. The Riemannian circle is introduced to present the gradient relationship of transformed nonlinear waves. When the phase shift produced by the elastic collision of two-soliton or two-breather is large but limited, the two V-shaped structures of two-soliton or two-breather have significantly separated, accompanied by the formation of a branch connecting the two V-shaped solitons. Two quasi-resonant interactions, namely weakly quasi-resonance and strongly quasi-resonance are investigated. Based on the asymptotic analysis method, the properties of the resonant branch are analyzed in detail, including the trajectory, amplitude and velocity.

We formulate the problem as a boundary value problem governed by the mild-slope equation and employ the transfer matrix method to determine the scattering coefficients. Our analysis reveals that the number of bars and their spacing modulate Bragg resonance characteristics, with the number of sub-harmonic peaks between harmonic peaks being two fewer than the number of bars. For non-uniform bar arrays, rainbow reflection occurs, suppressing sub-harmonic peaks and eliminating multiple zeros in wave reflection. As the bar length approaches the water depth, wave diffraction becomes significant. Complete wave reflection by uniform bar arrays demonstrates a behaviour analogous to Fabry-Pérot resonance in optics. The Bragg reflection patterns exhibit distinctive properties: common zero minima for even numbers of bars and common maxima for odd numbers. When examining the inverse case — submerged trenches instead of bars — we observe similar harmonic and subharmonic components with consistent phase shifts and notably reduced reflected wave amplitudes. Wave field analysis demonstrates three distinct regions: standing waves on the incident side, progressive waves on the leeward side, and partly standing waves in the confined region between bars. The sloped geometries of the bar systems induce wave refraction and amplitude decay.
