摘要
沙力河大桥为先张法预应力混凝土空心板,通过现场静动力荷载试验,测得桥梁结构的力学指标和性能指标。对试验值与理论计算值进行比较分析,以评定该桥的实际承载能力及现有技术状况,进而验证该桥的设计质量,评定该桥的施工质量,并为该桥的竣工验收及后期的安全运营提供科学依据。
Shali River Bridge was built using prestressed hollow core slabs. The dynamic indexes and performances of Shah River Bridge were obtained through the onsite static and moving load experiments. The carrying capacity and technical conditions of this bridge were assessed according to the test results by comparing with the theoretical values, and then the design and construction quality were valued, which provides a scientific basis for the complete acceptance and safe operation.
