半整体式桥台无缝桥的结构分析及其应用研究
|
摘要
桥头和桥梁伸缩缝处的跳车现象在公路桥梁中大量存在，严重影响公路的营运水平，并损伤桥梁及路面结构，增加其维修和养护费用。研究避免或减少桥台跳车的技术及处理措施具有重要的工程实用价值。本文采用理论分析与工程实践相结合的方法对这一课题进行了较为系统的研究。
通过实际调查，分析了桥头跳车和桥梁伸缩装置处跳车产生的主要原因及其综合防治措施，认为必须把桥台自身结构的改进与台后设计相结合，综合进行跳车防治；运用半整体式桥台原理进行了平顶山市石龙河桥的全桥无缝设计和建筑施工，并对其施工技术进行了研究，对其关键部位进行了测试；对半整体式桥台及台后结构进行了理论分析，提出了桥台——搭板——台后土共同作用的空间计算模型，其计算结果与实际测试结果吻合良好。
工程应用的成功证明：本课题半整体式桥台全无缝桥的理论分析是正确的，工程施工技术是可行和可靠的，可以有效的避免桥台跳车的发生，具有明显的经济效益。半整体式桥台全无缝桥有着广阔的应用前景。
The phenomena of abutment staggering are always occurred in highway bridges. This severely affects the operate level of highway, and damages the structure of bridge and pavement, and increases the maintenance costs. Study technique measures to avoid and lessen abutment staggering is most worthy of doing for the engineering appliance. This paper use method of combining theory research with engineering. The factors that cause staggering in the bridge end and the location of expansion and contraction installation and the synthetic measures of prevention and lessening are analyzed. Improvement of the abutment structure design must combines with design of the abutment back. Using theory of semi-integral abutment, the jointless bridge, Shilong River Bridge, is designed and constructed. Some parameters in key part of bridge are tested.
Theory of the semi-integral abutment structure and the abutment back structure are analyzed. The space computing modal of abutment-run-on slab-abutment back soil interaction is advised. The compute results are consistent with the practice results. The success of the Shilong river Bridge proves: the theory analysis of semi-integral abutment jointless bridge is right in this study, and construction technique of it is feasible and reliable, and this measures is effective for avoiding and lessening abutment staggering and is visible economized. The technique of semi-integral abutment jointless bridge has a bright future.
