某钢筋混凝土拱桥无损检测与荷载试验

该桥为一座已使用20余年的钢筋混凝土拱桥。为了全面了解该桥现有状况，对该桥进行了无损检测与荷载试验，以期评估现有桥梁状况，判断桥梁的承载能力。通过检测和试验，为该桥是否能够进行扩宽以适应道路扩建的需要提供了依据，同时可供该类现有桥梁的维护使用和加固改造工作借鉴。

Non-mar detection and loading test for a reinforced concrete arch bridge

The bridge is an old reinforced concrete arch bridge what has been used for nearly 20 years.By the reason of rebuilding road,it is necessary to check the work state of this bridge.So a Non mar detection and loading test was applied,to evaluate the work state and judge carrying capacity of the bridge.Through the detection and test on this bridge,it is hoped to decide whether the bridge can be widen to adapt the demand for the bridge's rebuilding.By the way,the results here delivered may be helpful for the same kind of reinforced concrete arch bridge's refreshing and maintenance.
