摘要:
路基工程作为轨道基础是确保有轨电车运营车辆平稳、安全的重要因素，国内尚无统一的设计标准与结构形式。为此，对国内有轨电车路基设计标准的调研数据进行了统计分析。通过理论分析与模拟计算，得出较优的路基形式与设计参数；并经已运营的广州海珠环岛新型有轨电车试验段工程的应用，验证了研究成果；所提出的经济、适用的有轨电车路基设计标准，为类似工程提供了参考。
Abstracts:
As the track foundation, subgrade is an important factor to ensure the stability and safety of tram operation vehicles. However, there are no uniform design standards and structural forms in China yet. Through statistical analysis of the survey data related to tram subgrade design standards all over China, then according to theoretical analysis and simulation calculation, the optimum subgrade form and design parameters are obtained, which are applied to the new tram test section project in Haizhu Ring Island of Guangzhou and the research results are verified. The economic and applicable design criteria proposed for tram subgrade provide a reference for similar projects.
