玄武岩纤维筋水泥混凝土路面光纤观测分析

Optical Fibre Observation of CBFR Cement Concrete Pavement

结合理论研究成果,通过在纵向设置分布式光纤传感器,分析由于温度变化引起的纵筋内部应力变化情况;同时通过加载试验,了解玄武岩纤维连续配筋水泥混凝土路面在荷载作用下内部应力的变化情况,与理论计算结果进行比较,并修正理论分析模型,使得理论分析与实际受力相吻合。

Combining with theoretical research fruit,the change of inner stress of longitudinal steel bar ca-used by temperature change is analyzed through setting distributed fibre sensors in longitudinal dimension,and the change of inner stress of continuously reinforced CBFR cement concrete pavement under load is realized by loading test.Comparing the test result with theoretical result,the theoretical analysis model is modified,which makes the theoretical analysis accords with the actual force.
