【摘要】：本文通过张石公路三号地（冀蒙界）至张北段高速公路康保连接线K48+121大桥和K57+330中桥的工程实践，分别选取了一座预应力连续空心板桥和一座装配式预应力混凝土连续小箱梁桥作为研究对象，运用压路机——桥梁耦合振动的分析方法，对振动压路机与振荡压路机单独或联合作业下的几十种不同工况进行了测试，采集了不同位置的振动加速度、振动频谱、动位移、动应变及压实度等大量的数据，并对26种典型工况进行了重点对比研究和分析，研究振荡压路机在公路施工中特别是大跨径桥梁桥面摊铺中的应用情况。通过试验、测试和分析认为，振荡压路机完全能够满足沥青混凝土公路路面铺装施工的要求，尤其在桥面铺装施工中具有其独到的优越性。本研究为今后公路路面特别是桥面沥青砼压实施工和施工压路机特别是振荡压路机的引进和更新，提供了理论依据。该研究成果可在新建、改建、大中修高速公路、一级公路沥青路面及薄层沥青混凝土路面、大中桥梁桥面施工中广泛应用，还可以推广应用到有地下管网的城市道路建设、城市多层停车场建设等工程，，带来显著的经济效益和社会效益。
[Abstract]:In this paper, through a stone road No. three (Hebei Mongolia circles) engineering practice to Zhangbei highway connecting line Kangbao K48+121 bridge and K57+330 bridge, were selected by a continuous prestressed hollow slab bridge and a prestressed concrete continuous box girder bridge as the research object, the use of roller - bridge coupling vibration analysis method, for dozens of different working conditions of vibratory and oscillatory roller alone or combined operations were tested, collected at different positions of the vibration acceleration, vibration spectrum, dynamic displacement, dynamic strain data and compaction number, and the 26 typical conditions were the focus of comparison and Analysis Study on oscillation roller in highway construction especially the application of long-span bridge deck paving process.
Through the experiment, test and analysis, oscillatory roller can fully meet the construction requirements of highway asphalt concrete pavement, especially has its superiority in bridge deck pavement construction. This research for the future of highway pavement construction of asphalt concrete deck especially compaction and construction of roller especially introduce and update the oscillatory roller the machine, which provided a theoretical basis. The research results in the new construction, renovation, maintenance of highway, a highway asphalt pavement and thin asphalt concrete pavement, widely used in large and medium-sized bridge deck construction, can also be popularized to the underground pipe network of city road construction, city parking lot construction engineering, bring significant the economic and social benefits.
