深中通道岛隧结合部波流特性及覆盖层稳定性试验研究
Experimental study on wave current characteristics and cover layer stability at island tunnel junction of the Shenzhen-Zhongshan Channel Project
摘要
Abstract
Based on the significant differences between the junction of island tunnel engineering and traditional tunnels and nearshore engineering,as well as the many new challenges faced in design,research was conducted to ensure the safety and reliability of the coverage layer of the immersed tube tunnel at the junction,as well as the wave current characteristics and stability of the protective structure within the region.Physical model experiments were conducted to simulate the hydrodynamic field,encompassing wave-flow angle variations and the stability of armor blocks under wave-current coupling.These experiments revealed the wave-current coupling effect at the island tunnel junction,yielding variation patterns of wave height ratio(H'/Hs)and flow velocity ratio(U'/U)relative to flow velocity(U/C),wave steepness(Hs/L),relative water depth(d/L),and wave-current angle(α).Corresponding calculation formulas were derived.Through comparative analysis and optimization of multiple experimental sets,the optimal stable weight of the armor blocks was determined,and a formula for calculating this stable weight under wave-current coupling was derived.This paper not only solves the practical problems of the major project of the deep-to-medium channel but also provides valuable basic data and technical support for the construction of the cover layer of submarine immersed tunnels in the future.关键词
