间隔嵌岩板桩结构在越南永安港码头中的应用

Application of interval rock socketed sheet pile structure in wharf of Vietnamese Yong’an Port

以越南永安港5#、6#通用泊位工程建设为依托,根据该区域波浪条件差、地质条件复杂等特点综合比选高桩梁板式结构、重力式沉箱结构、板桩式结构等以确定最优的码头结构方案,对工程区域沉桩可行性进行深入研究,并使用Plaxis软件进行结构计算。结果表明,工程推荐采用前墙间隔嵌岩钢管桩、钢拉杆锚定墙板桩式码头结构,该结构方案是安全的,其内力、位移可控。

Based on the construction of 5#and 6#general berths in Vietnamese Yong’an Port,we compare high pile beam slab structure,gravity caisson structure and sheet pile structure to determine the optimal wharf structural scheme according to the characteristics of poor wave conditions and complex geological conditions,further study the feasibility of pile sinking in the project area,and carry out structural calculation by the software Plaxis.The results show that it is recommended to adopt the front wall interval rock socketed steel pipe pile and steel tie rod anchored wall plate pile wharf structure.This structure scheme is safety,and the internal force and displacement can be controlled.
