钢筋混凝土撑架连续板桥设计最先见于澎河桥,澎河桥位于许昌地区鲁山县,该桥为9孔净跨15.2米,全长149.2米,撑架与水平线夹角为32°。于1975年2月建成,当年夏天曾受到一次特大洪水的考验(水位平桥面)。通车后至今运行情况良好。西安公路学院曾协同许昌总段在该桥做了静载试验和结构分析试验,试验结果表明该桥结构的刚度良好,具有足够的安全度。但从实测取得
The design of continuous slab of reinforced concrete frame is first seen in Penghe Bridge. The bridge of Penghe is located in Lushan County of Xuchang. The bridge has a 9-hole net span of 15.2 meters and a total length of 149.2 meters. The angle between the support and the horizontal is 32 °. Built in February 1975, the summer of that year was subjected to a major flood test (water level bridge deck). Since the opening operation has been good. Xi’an Highway College has collaborated with Xuchang segment to make static load test and structural analysis test on the bridge. The test results show that the bridge structure has good rigidity and sufficient safety. But from the actual measurement
