“一带一路”背景下中泰高铁建材标准差异化研究

Study on Difference of Construction Material Standards for China - Thailand High-speed Railway under Background of "One Belt, One Road"

摘要:

为了解决中资企业出海过程中遇到的中国标准水土不服问题，以中泰高铁项目推进中遇到的中国标准属地化问题为例，运用理论对比和试验分析等方式对中泰两国高铁建设最常用的钢筋和混凝土材料标准异同点进行了系统研究，旨在为“一带一路”政策下中国标准全球化推广提供有意义的参考，结果表明：中国标准中关于钢筋屈服强度、断裂后伸长率要求和磷、硫、碳元素含量相关规范限值均高于泰国工业标准要求，且泰国钢筋直径规格对比中国钢筋规格标准偏少；试验后发现经过工序改良后的泰国当地钢筋完全满足中国相关强制性标准要求；泰国混凝土相关缺少对其弹性模量、抗拉性能和长期耐久性等层面要求，需要与当地业主统筹中国标准的属地化落地问题。

Abstract:

In order to solve the problem of Chinese standards not adapting to local conditions encountered by Chinese enterprises in the process of going overseas, taking the localization of Chinese standards encountered in the promotion of the China-Thailand High-speed Railway Project as an example, the theoretical comparison and experimental analysis are applied to systematically study the similarities and differences in the standards of the most commonly used steel bars and concrete materials in the construction of the high-sped railway projects of China and Thailand, which aims to provide a meaningful reference for the global promotion of Chinese standards under the policy of "One Belt, One Road". The result shows that the requirements for steel bar yield strength, elongation after fracture, and the relevant specification limits of phosphorus, sulfur, and carbon content in Chinese standards are higher than those in Thai industrial standards, and the diameter specifications of Thai steel bars are less than those in Chinese steel bar specifications. The test results show that the local Thai steel bars after process modification fully meet the requirements of relevant Chinese mandatory standards. There is a lack of requirements for the elastic modulus, tensile performance and long-term durability of concrete in Thailand. It is necessary to coordinate with local property owners on the localization implementation of Chinese standards.
