摘要
为检验石—太汽车专用公路小米峪桥的实际性能，特开展了16米足尺梁的静载破坏试验，实测了梁的开裂荷载，裂缝发展及闭合情况，挠度及无粘结力筋极限应力和破坏荷载等。根据试验结果，对有关问题进行了叙述和讨论。
For verifying the serviceability of Xiaomiyu bridge on Shijiazhuang to Taiyuan special roadway,the static load experiment of 16-meter unbended partially prestressed conorete beams is carried out. The crack load, crack developing and closing, deflection, the limit stress of reinforcement and the beraking load of the beam are observed. Some relevant problems are also described and discussed.
