摘要
我国的技术规范建议沉箱前趾不宜过大,而国外出现超大前趾沉箱结构的实际案例。基于国外某实际工程案例,采用中国规范对沉箱结构码头的整体稳定性及基床应力进行分析,并对比算例中超大前趾和我国常规前趾沉箱的各项结构性能指标,得出超大前趾沉箱结构具有一定的结构优越性,对我国沉箱结构的优化设计具有参考价值。
Chinese code recommends that the footing of the caisson should not be too long,while the caissonwith large footing has been applied abroad.This paper checks the overall stability and foundation bed stress of thecaisson with large footing by the Chinese code,which makes comparison with the caisson with normal footing.According to the comparison,the caisson with large footing has great advantages,which has certain reference valuefor the design optimization of caisson in the future.
