The main contents and results of this paper are listed as follows:Based on the finite element analysis software ANSYS establish a bridge of three-dimensional mechanical model of CWR;Based on an actual project,calculate different conditions of three forms of bridge and research the reasonable removal scope of fastener;Research on the allowed lock temperature rail track construction of partial maintenance of range.By analyzing the result obtain the best way to replace the support of a bridge and the range of removal of the bearing and permission of rail temperature of construction.It supports some recommendations for the replacement of city construction maintenance.

本文主要研究内容为：基于有限元分析软件ANSYS建立了桥上无缝线路三维力学模型；依据某实际工程，分析计算了三种桥梁形式在不同顶升工况下的钢轨和扣件受力，研究了扣件的合理拆除范围；对维修后局部钢轨施工锁定轨温的允许范围进行了研究；分析得出了城轨桥梁更换支座施工的最佳顶升方式、扣件拆除范围和允许施工轨温，为城轨桥梁更换支座的施工维修提出了一些建议。

The study indicates: the larger of the pressure of the rubber bearing, the weaker of the gliding capability of the rubber bearing. However, because the rubber bearing can rotate freely, the effect of minishing the stress of temperature and shrinkage is also very apparent.

研究表明，橡胶支座处的压力越大，橡胶支座的滑动能力越差，但由于可以自由转动，降低温度及收缩应力的效果仍然比较明显。

本文着重介绍准连续 T型梁桥支座替换工程施工技术，并分析支座病害原因。

The engineering rubber product cover 4 big series into more than 100 kinds in over 1,000 spec fications,,including rubber water stop, plate bearing, pot bearing, expansion joint and restrainers, covering 43 percent of the national markets.

工程橡胶产品又涵盖了橡胶止水带、板式支座、盆式支座、桥梁伸缩装置四大系列100多个品种、1000多种规格，占据了全国43%以上的市场份额。

The closed ring confining truss is set along the periphery of the reticulated shell, and the stiffening truss is set in the middle single-layer shell which can take advantage of the architectural shape. These measures resolve the contradiction between overall stability and temperature stress, and also avoid the shell thrust act on the lower concrete structure directly. Besides, these measures simplify the design of the shell bearing and the concrete structure, and the cost of the concrete structure can also be saved.

网壳通过可径向滑动球铰支座与下部混凝土结构连接，网壳周边设置封闭环形约束桁架，中间单层壳体部分利用建筑凸肋造型设置加劲桁架，解决了保证整体稳定和减小温度应力之间的矛盾，同时避免了网壳侧推力直接传递给下部混凝土结构，简化了网壳支座及下部混凝土结构的设计，节约了混凝土结构的造价。

According to the characteristics of large span structure design, such as big diffrence of collumn force, large span and spacious roof, week linkness of different parts and large displacement of bearing, spacil structure methods such as different types of concrete pile with different length, suitable joint and bearing are adopted to achieve the economical and safe demand
