在缺乏可借鉴的设计经验和技术标准条件下,通过不断探索和创新,在武广铁路客运专线乌龙泉至韶关段无砟轨道路基设计中成功运用了“路堤式路堑”结构、各类“过渡段路基”设计、路基站后附属结构物接口设计、冲击压实技术、桩帽式CFG桩复合地基、桩-网结构、路堑高边坡预加固技术、挂网喷混植生及土工合成材料的推广应用等一系列新技术、新材料,将为我国长大客运专线路基设计标准及规范的制定和完善提供有益参考。
In the absence of design experience and technical standards that can be used for reference, through continuous exploration and innovation, the “embankment-type cutting” structure has been successfully used in the design of ballastless track subgrade at Wulongquan-Shaoguan section of Wu-Guang Railway. Class “transition section embankment ” design, interface design of sub-structures of subgrade, impact compaction technology, pile-cap CFG pile composite foundation, pile-net structure, high slope pre-reinforcement technology, And the popularization and application of geosynthetics and a series of new technologies and new materials will provide useful reference for the formulation and improvement of design criteria and specifications for subgrade for the growth of passenger dedicated lines in China.
