欧标体系下码头打入桩施工前期策划及工作流程

Preliminary planning and work process of pier's driven pile construction under European standard system

码头打入桩施工前期的策划主要包括选择打桩设备、制定沉桩控制标准和现场试验等,是打入桩设计施工能否顺利实施的关键。而中、欧标准的差异会让熟悉国内标准的中国工程师对欧标体系下打入桩施工前的策划工作感到困扰。从规范条文出发,介绍欧标体系下码头打入桩施工前期的主要策划工作,并通过与中国规范相关内容的对比,总结中、欧标准的异同以加深对欧洲标准的理解。以此提出欧标体系下打入桩施工前期的主要工作流程,并在东非某码头工程中进行应用。工程实践表明,该流程有理有据、内容全面,能满足采用欧洲标准项目的要求。

The planning work in the early stage of the wharf's driven pile construction includes the selection of driving equipment,establishing pile driving control standards and pile test,etc.,which is the key to the success of driven pile design and construction.The differences between Chinese and European standards will make Chinese engineers who are familiar with the domestic standards perplexed by the preparation work before the construction of driven piles under the European standard system.Starting from the standard,this article introduces the main planning work in the early stage of the pier's driven pile construction under the European standard system,and through comparison with the relevant content of the Chinese standard,summarizes the similarities and differences between the Chinese and European standards to deepen the understanding of the European standard.In this way,the main work process in the early stage of driving pile construction under the European standard system is proposed and applied to a terminal project in East Africa.The engineering practice shows that the process is well-founded and comprehensive,and can meet the requirements of adopting European standard projects.
