摘　　要：通过对遂渝线无砟轨道综合试验段双块式现浇混凝土道床板裂缝和嵌入式支撑块周围道床破损现象的研究，从施工、养护维修和运营状况等方面分析了现浇混凝土道床板裂缝和嵌入式支撑块周围道床破损的成因，提出了防治双块式无砟轨道道床板裂缝和嵌入式支撑块周围道床破损的具体施工方案，以期对我国已经建成的各条高速铁路和客运专线现浇混凝土道床板裂缝及嵌入式支撑块周围道床破损的病害整治有所裨益。Based on the study of double block type cast -in -situ concrete track slab crack and embedded aroundthe support block track damage phenomenon in Sui - Yu ballastless track integrated experimental section, it discusses the causes from the construction, maintenance, repairing and operation condition. And it proposes the actualconstruction scheme of prevention and control of it. Therefore do something helpful to cure and prevent cast - in - place concrete track slab cracks and embedded supporting block track damage around the disease treatment forthose built high -speed railways and passenger dedicated lines in our country.
