This paper describes the application of semi - circular breakwater at home and abroad and the design innovation and optimization of semi - circular jetty in yangtze estuary deepwater channel regulation project , esp . the design of estuary jetty structure using semi - circular floating caissons ; a new calculation method for wave forces acting on the submerged semi - circular estuary jetty and the optimization design method for semi - circular structures are recommended 摘要介紹半圓型防波堤和河口導(dǎo)堤在國內(nèi)外的應(yīng)用概況及在長江口深水航道治理工程中對半圓型導(dǎo)堤的設(shè)計創(chuàng)新和優(yōu)化半圓型浮式沉箱的導(dǎo)堤結(jié)構(gòu)型式,提出堤頂淹沒情況下半圓型導(dǎo)堤波浪力的計算方法以及半圓型結(jié)構(gòu)的優(yōu)化設(shè)計方法等。
The results indicate that the towage of pneumatically floated caisson - cylindrical structures and the towage of integrated caisson - cylindrical structure with superstructure installed prove to be feasible technically , technologically and safely and that the methods established for the analysis and calculation of the stability of pneumatically floated structures are rational 結(jié)果表明:基礎(chǔ)箱筒氣浮拖運與拼接上部結(jié)構(gòu)后整體箱筒氣浮拖運在技術(shù)、工藝、安全上都是可行的,所建立的氣浮穩(wěn)性分析和計算方法是合理的。
