摘要
根据CRTSⅡ型板式无砟轨道的技术特点和山区铁路施工的特点,结合国内首条山区高铁CRTSⅡ型板式无砟轨道施工建设,总结出山区CRTSⅡ型板式无砟轨道施工的特点和施工中面临的实际困难,建议建设单位和设计单位等降低山区高铁无砟轨道铺设进度参考指标,提高成本概算指标,同时施工单位应加强证据收集,以争取合理的施工成本。
Based on the technical characteristics of CRTSⅡ rail slab and construction characteristics of high speed railway line in mountainous,combined with the first rail slab construction in mountain area,the paper points out the construction characteristics of CRTSⅡ rail slab in mountain area and the real difficulties in construction,then puts forward advices to reduce the progress reference index for ballastless track of high speed railway in mountain area and increase the gross cost index.Moreover,construction organization should strengthens the collection of evidence to strive for reasonable cost of construction.
