摘　　要：为保证京沈客专工期,某施工标段采用CRTSⅢ型板式无砟轨道自密实混凝土冬季施工技术。介绍了该标段在施工自密实混凝土过程中,从原材料储存、运输过程、施工过程、成品养护四个方面所做的保温措施及温度监控工作。采用该工艺施工的CRTSⅢ型板式无砟轨道自密实混凝土经检测符合后续施工工艺要求,对类似工程有借鉴意义。To ensure the construction duration of the Beijing-Shenyang Passenger-oriented Railway,a certain construction contracted section adopts the winter construction techniques for self-densified concrete for Type-CRTS III slab non-ballasted tracks.Introduced in detail in the present paper are the temperature-maintaining measures taken and temperature-monitoring work done by the contracted section in the construction of the self-densified concrete in the process of storing raw materials,transporting,construction and curing the finished products.After being tested,the self-densified concrete for Type-CRTS III slab non-ballasted tracks built with the construction process is found to be in agreement with the requirements of the following processes in technology.The project may serve as a useful reference for other similar projects.
