摘　　要：交通基础设施建设是共建“一带一路”倡议的重要内容,面向“新工科”的国际化人才培养是“一带一路”中国倡议走向国际实践的原动力。课程以“交通强国”课程思政为教育教学基本理念,围绕桩网结构路基的工作机理和土拱效应的发挥机制进行教学设计。从经典桩网结构路基工程案例分析出发,讲授和讨论宏微观土拱效应试验结果,运用数值模拟手段进行延伸教学,构建“多模块、多层次、全过程、多途径”的国际化课程教学和实践体系,促进力学基础理论、工程实践能力、创新教育的教学路径融合,提升学生的国际化能力,以适应土木工程专业的快速发展和国际市场的人才需求。Transportation infrastructure is important to the“the Belt and Road Initiative”.The motivation of initiative sponsored by China originates from the international talent cultivation for the“New Engineering”.With the development of transportation engineering,a country with strong transportation network is an important moral education and intellectual education,and teaching designs of performance of geosynthetic-reinforced and pile-supported(GRPS)embankment as well as the mechanisms of soil arching effects are conducted.Based on the classical engineering cases of GRPS embankment,both laboratory tests and numerical simulations to model macro-micro soil arching effects are added into the multi-module international teaching course of embankment engineering,which contributes to improve the mechanical theoretical knowledge,the practical ability and the innovation education level of civil engineering students.The intellectual level and engineering attainment of civil engineering students can be promoted in order to satisfy a quick development of civil engineering and requirements of international labor market.
