摘　　要：随着我国港口事业的快速发展,天然良港的港址越来越少,而重力式码头由于其自身的优越性,在可能的情况下,通常都优先考虑,因此近年来出现一批深基床、大开挖的码头,而规范仅明确深基槽可以采用换填的方式处理,并未明确换填基槽开挖的底宽。论文根据工程实例,对如何设计换填基槽开挖底宽进行了分析。With the rapid development of the ports and harbors, the good natural harbor sites are rarely in the coastal areas. Because of gravity quays＇ own superiority, which made gravity quays always a better choice where is possible. So, there are appeared large excavation gravity quay, though there are proposed using replacement under foundation bed in code, and it didn＇t give the method how to design the excavation width at this condition. This paper summarized studies on the excavation width optimization in project.
