摘要
近年来,我国的施工企业在“一带一路”沿线国家承揽了较多码头工程,但因对国外规范了解不够深入,给施工开展带来很大困扰。以中国码头施工规范和欧洲灌注桩执行规范EN1536为例,详细比较中国和欧洲两套现行规范在码头钻孔灌注桩施工中部分条款之差异,主要结果有:1)中国规范对桩的分类与欧洲规范或学术方法不一致。2)欧洲规范规定钻孔灌注桩的一般原则,中国规范则有比较细致的定量指标。3)欧洲规范对桩的承载力和完整性检测要求有规定,而中国规范相关要求较少。相关比较对我国施工企业开展国外码头建设有所裨益。
Chinese construction enterprises have undertaken many wharf projects along the“One Belt and One Road”countries in recent years.However,lack of in-depth understanding of foreign codes brings great trouble for the construction.Taking the construction code for wharf structures of China and the execution code for bored piles of Europe EN 1536 as examples,the differences of certain part about bored cast-in-situ piles between the two codes are compared in detail in this paper.The main conclusions are as follows:1)The classification of piles in Chinese code is different from that in European code or academic method.2)The European code establishes general principles for the execution of bored cast-in-situ piles,while there are more detailed quantitative indicators in Chinese code.3)The European code specifies the requirements for pile bearing capacity and integrity testing,while the Chinese code has fewer requirements.Related comparisons are beneficial for Chinese construction enterprises to carry out foreign wharf projects.
