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堤在國內(nèi)外的應用概況及在長江口深水航道治理工程中對半圓型導堤的設計創(chuàng)新和優(yōu)化半圓型浮式沉箱的導堤結構型式,提出堤頂淹沒情況下半圓型導堤波浪力的計算方法以及半圓型結構的優(yōu)化設計方法等。
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 結果表明:基礎箱筒氣浮拖運與拼接上部結構后整體箱筒氣浮拖運在技術、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。
