摘要
笔者对铁路桥梁用空心无配筋活性粉末混凝土人行道板进行了抗弯试验研究 ,探讨了其受力变形性能。分析表明 :活性粉末混凝土人行道板的安全系数均大于 2 ,满足承载能力要求 ;位移延性系数均大于 3.5 ,具有良好的延性性能 ,破坏形式属于延性破坏。该类人行道板的成果已通过铁道部专家的鉴定 ,拟用于青藏铁路桥梁实际工程中。
Thirteen RPC200 foot-slabs without steel reinforcements were tested under four-point loading to investigate the flexural behavior. The results showed that 1) the safety coefficient of RPC200 slabs was greater than 2 and met the requirement of carrying capacity; 2) the ductility factors of RPC200 slabs were greater than 3.5, so the slabs possessed excellent ductility. These slabs would be applied to Qingzang railway bridges.
