桥头

In recent years, a new type of flexible abutment is applied to the projects and it may prevent differential settlement radically.

近年来 ，加筋土结构的柔性桥台开始应用于工程实践，这种结构有可能从根本上防止桥头跳车的产生。

With the construction of highway developing in the mountains, high filling embankment behind abutment will be inevitably encountered.

随着高等级公路建设在山区的开展，不可避免地会遇到桥头高填路基问题。

The paper is based on the construction of the express - highway between yiyang and changde in hunan province , aiming at enhancing the serviceability of cement concrete pavement , probing into the structural assemblage of the cement concrete pavement , the roadway drainage system , contraction joint with the dowel bar and precaution of bumping at the end of the abutment . it presents some achievements of the research , including more reasonable structural assemblage and roadway drainage system , the method of setting dowelled bar in contraction joint , putting forward the concept of stage - transition from rigid to flexile behind abutment

本文以湖南省益阳至常德高速公路项目为依托，以提高水泥混凝土路面使用性能为目标，就水泥混凝土路面结构组合、路面排水系统、缩缝设置传力杆、桥头跳车问题的防治等方面开展研究和工程实践，取得了丰富的研究成果，如研究采用了更合理的路面结构组合，设置了较完善的路面排水系统，在国内高速公路上率先全面采用缩缝加传力杆技术，对所有桥涵构造物台背全部采用刚柔过渡技术处理桥头跳车问题等。

The Army Group North ordered the deployment of the army detachment "Narwa" on February 22 in the following positions: III SS Panzer Corps deployed to Narva, Ivangorod Bridgehead on the east bank of the river and north of Narva; the XXXXIII Army Corps against the Krivasoo Bridgehead south of the city and the XXVI Army Corps to the sector between the Krivasoo and Lake Peipus.

这个集团军北下令部署军队支队"纳尔瓦"2月22日在以下位置：第三装甲团部署到纳尔瓦，伊万哥罗德桥头东岸的河以北的纳尔瓦；的XXXXIII军团反对Krivasoo桥头以南城市和第二十六军团的部门之间的Krivasoo和湖佩普西湖。

In the practice we have no special design of the approach slap , and the theoretical thereunder is not so reasonable. For example, when calculate the length of the approach slap, we adopt the permission differential change slap and settlement, without considering the height of road embankment filling , the form of abutment and the properties of the filling sort, so sometimes it is hard to eliminate the bridge head bump completely because of the disjoint, rupture or overshort of the approach slap, influencing the use of the road and bridge.

实践中一般桥头搭板不作专项设计，且理论依据不甚合理，如搭板长度计算采用桥头容许变坡差和沉降量确定，没有考虑路堤填土高度、桥台形式及填土性质，所以有时会出现搭板脱空、断裂或过短而未能彻底消除跳车现象，从而给道路桥梁的使用带来影响。

On the basis of detail analyzing the cause and influence factors of the approach slap design, this paper which utilize the flexible ground beam theory and finite element numerical calculation method to calculate the ground reaction、internal force and bending deflection, in each condition of disjoint and undisjoint of the approach slap near the abutment end, with the different ground module and length of the approach slap, achieves some valuable conclusions.

本文在对桥头跳车成因和桥头搭板设计影响因素作了详细的分析基础上，运用弹性地基梁理论和有限元数值计算方法，对桥头搭板在近台端不脱空和脱空时，在不同的地基模量及不同的搭板长度，搭板任意截面的地基反力、内力及挠度大小进行计算，得出了一些有意义的结论。
