[提要]  在1940年代，美國(guó)德克札高( TEXACO)石油公司在洪都拉斯國(guó)北方海岸建有一個(gè)鋼結(jié)構(gòu)的原油碼頭。1998年德克札高公司在原來(lái)的舊址重建新碼頭和岸邊的引橋。新原油碼頭工程采用預(yù)制預(yù)應(yīng)力混凝土樁基礎(chǔ)。上部結(jié)構(gòu)采用預(yù)制和現(xiàn)澆混凝土疊合結(jié)構(gòu)。施工中基本免除了現(xiàn)場(chǎng)的模板工程作業(yè)，大大提高了工程質(zhì)量，縮短了施工周期。介紹這一設(shè)計(jì)的特色及施工和安裝中的要點(diǎn)，其創(chuàng)新設(shè)計(jì)觀念給碼頭工程和海工結(jié)構(gòu)的傳統(tǒng)設(shè)計(jì)提供了新的思路。

The Texaco Whart maritime Port Facility is a major marine docking structure located off the northern coast of Honduras that has replaced a 1940's steel frame docking structure and access bridge. The structure comprises precast concrete piling and superstructure components that combine precast and cast-in-place concrete. The construction methodology almost completely eliminated the need for on site formwork and proved to be very successful in producing a high quality docking project in a short time frame. This article presents the design parameters, construction challenges, and erection highlights of the project.
