摘要
桥涵伸缩缝装置安装后发生的病害严重影响车辆的正常通行,需要对伸缩缝不断维修,从而提高了工程造价.针对这种缺陷,应选择优良的伸缩缝弹塑体材料.采用美加和美加改性的对比试验的研究方法,对弹塑体材料各种基本性能进行了分析,可以看出弹塑体材料作为伸缩缝的主体材料具有良好的性能,在现实应用中具有重要的意义.
The problems caused by installing the expansion and contraction devices of bridge will have a strong impact on the operation. So the expansion and consraction need constant mainte-nance and construction cost will be increased. To overcome these defect, It is crucial to choose the best elastoplastic materails. Through the contradistinctive experimental study of MJ and MJ modified, our work is to make the experimental analyses of fundamental characteristic of elasto-plastic materails in this paper. The elastoplastic materails used as host material of expansion and contraction have good performance.
