随着CRTS Ⅲ型板式无砟轨道修建里程逐年增长,钢筋混凝土底座板容易开裂.底座板裂缝的出现将导致混凝土和钢筋容易受到外界环境侵蚀,严重影响耐久性.文中探明底座板开裂的原因,进而提出有针对性的预防措施.
Cause Analysis and Preventive Measures of CRTS Ⅲ Type Plate Ballastless Track Base Plate Cracking
With the increasing construction mileage of CRTS III slab ballastless track year by year,reinforced concrete base plates are prone to cracking.The occurrence of base plate cracks will lead to concrete and steel bar vulnerable to the external environment erosion,seriously affect the long-term durability.It is the main problem of this research to prove the cause of base plate cracking and then put forward targeted meas-ures to prevent early cracking.
