摘　　要：通过对道岔捣固车在养护作业中及作业后地岔枕受力影响的现场测试数据进行了分析 ,为预应力钢筋混凝土岔枕在列车提速、大型捣固机作业等条件下提供实测数据 ,从而对钢筋混凝土岔枕的强度作出评价 .Based on the engineering practice, the mechanical behavior of the reinforced concrete sleeper caused by ramming machine is studied. Under high speed of the train and construction of the large ramming machine, the strength of reinforced concrete sleeper, which has been checked by a case record on the site, is strong enough.
