Description

中低速磁悬浮交通工程低置线路双线地段承轨梁节间限位结构Mid-low speed magnetic levitation traffic engineering low-line two-line section bearing beam inter-section limit structure [技术领域][Technical field]
本发明属于中低速磁悬浮低置线路领域，更具体地，涉及中低速磁悬浮交通工程低置线路双线地段承轨梁节间限位结构。The invention belongs to the field of medium and low speed magnetic levitation low line, and more particularly relates to an inter-segment limit structure of a track-bearing beam in a low-line two-line section of a medium-low speed magnetic levitation traffic engineering.
[背景技术][Background technique]
中低速磁悬浮轨道交通属于一种新型交通方式，目前国内外的研究成果较少，全世界开通运营的线路更是少数。目前只有2005年3月日本建设开通的中低速磁悬浮铁路商业运行线-东部丘陵线和2014年6月韩国开通的中低速磁悬浮铁路商务运行线。而中国的中低速磁悬浮交通目前只有国防科技大学试验线、青城山试验线、唐山实验线，但没有投入运营的正式线路，且均以高架结构为主，鲜见有关低置线路承轨梁结构方面的研究与应用。Medium- and low-speed magnetic levitation rail transit is a new type of transportation. At present, there are few research results at home and abroad, and the number of lines opened and operated in the world is even rare. At present, there is only the commercial operation line of the medium and low-speed magnetic levitation railway opened in March 2005 in Japan - the eastern hilly line and the medium and low speed magnetic levitation railway commercial operation line opened in June 2014 in South Korea. China's medium and low-speed magnetic levitation traffic is currently only the National Defense University of Science and Technology test line, Qingchengshan test line, Tangshan experimental line, but there is no official line of operation, and the main structure is elevated structure, rarely related to the low-line line bearing beam structure Research and application.
常规普速轮轨铁路中，线路对变形的适应能力大，对路基的沉降控制标准要求相对较松，因而有大量的线路修建在填土路基上；目前的无砟轨道高速铁路，尽管对线下路基的工后沉降要求十分严格，仍有不少线路修建在填土路基上，要求线下路基按构筑物修建，具有足够的强度与抗变形的能力，在各种自然环境下长期稳定。而中低速磁悬浮交通线磁悬浮列车采用“抱轨行驶”的方式运行，中低速磁悬浮交通线的F轨是由一节节短轨现场拼接而成，并留有轨间缝，要满足磁悬浮列车F轨的平稳运行的要求，就必须靠轨下低置线路结构保证，因而，磁悬浮交通线路对轨下基础的变形控制标准以及平顺性的要求更高，特别是对于两条铁路线并行的双线结构，其轨下基础的变形控制标准的控制尤其重要。In the conventional general-purpose wheel-rail railway, the line has great adaptability to deformation, and the settlement control standard for the roadbed is relatively loose. Therefore, a large number of lines are built on the fill roadbed; the current ballastless track high-speed railway, although the line The post-construction settlement requirements of the subgrade are very strict. There are still many lines built on the fill roadbed. It is required to construct the subgrade under the structure according to the structure. It has sufficient strength and resistance to deformation and is stable for a long time in various natural environments. The medium and low-speed magnetic levitation traffic line maglev train runs in the "holding track" mode. The F-track of the low-speed magnetic levitation traffic line is formed by a section of short track on-site splicing, and the inter-rail seam is reserved to meet the maglev train F. The requirement for the smooth operation of the rail must be ensured by the low-line structure under the rail. Therefore, the magnetic levitation traffic line has higher requirements for the deformation control standard and the smoothness of the under-rail foundation, especially for the two railway lines in parallel. The structure, the control of the deformation control standard of the underlying foundation is especially important.
为了防止过大的温度应力和不均匀沉降，传统的承轨梁结构一般采用每节10～30m设置伸缩缝，承轨梁下基础是由岩土构成的土工结构物，受地形、地质条件等因素的影响，质量相对不易控制，因此在荷载及各种自 然和各种自然因素作用下易产生不均匀沉降，相邻承轨梁之间难免会出现不一致的工后沉降，导致承轨梁产生错台，从而影响F轨的平顺性，甚至可能导致F轨产生错台、变形等问题，严重时将影响磁悬浮车辆的正常运营。In order to prevent excessive temperature stress and uneven settlement, the traditional bearing beam structure generally adopts expansion joints of 10 to 30 m per section. The foundation under the bearing beam is a geotechnical structure composed of rock and soil, subject to terrain and geological conditions. The influence of factors, the quality is relatively difficult to control, so in the load and various self However, under the action of various natural factors, uneven settlement is easy to occur, and inconsistent post-construction settlement will inevitably occur between adjacent bearing beams, resulting in misalignment of the bearing beam, thereby affecting the smoothness of the F-track, and may even lead to F. Rails cause problems such as misalignment and deformation, which will affect the normal operation of the magnetic levitation vehicle in severe cases.
