摘要
印度尼西亚雅加达至万隆高速铁路采用了CRTSⅢ型板式无砟轨道结构,而CRTSⅢ型板式无砟轨道由我国自主研发,已广泛应用于我国高速铁路。结合我国高速铁路相关研究成果,通过分析雅万高铁沿线气候环境特点和无砟轨道结构设计荷载差异,深入研究雅万高铁CRTSⅢ型板式无砟轨道结构优化方案。研究结果表明:雅万高铁可采用普通钢筋混凝土轨道板;轨道板最大温度梯度宜取0.65℃/cm,底座整体温差宜取15℃;优化后轨道板和自密实混凝土层配筋率可降低约10%;路基地段底座分段长度宜取4~6块轨道板。
Indonesia's Jakarta-Bandung high speed railway adopts CRTSⅢslab ballastless track structure.CRTSⅢslab ballastless track is independently developed by China and has been widely used in China's high speed railway.Combined with the relevant research results of China's high speed railway,through the analysis of the climate and environmental characteristics along the Jakarta-Bandung high speed railway and the design load difference of ballastless track structure,the structural optimization scheme of CRTSⅢslab ballastless track of Jakarta-Bandung high speed railway was deeply studied.The results show that the ordinary reinforced concrete track slab can be used in Jakarta-Bandung high speed railway.The maximum temperature gradient of the track slab is 0.65℃/cm,and the overall temperature difference of the base is 15℃.The reinforcement ratio of the optimized track slab and the self-compacting concrete layer can be reduced by about 10 percent.The base section length of subgrade section should be 4~6 track slabs.
