目前,地球的形势越来越严峻,人类所面临的挑战也越来越多,特别是自然灾害,比如说地震。在地震中,桥梁联结间的伸缩缝处就会发生过大变位的情况,因此成为造成桥梁破坏的直接原因,所以就需要在支座宽度不是特别大的伸缩缝间设置一个适当的限位装置,用来限制伸缩缝间的相对位移。本文通过对限位装置设计的方法进行了研究,从而达到其限位的目的。 At present, the situation on Earth is getting more and more serious, and human beings are facing more and more challenges, especially natural disasters, such as earthquakes. In the earthquake, the expansion joints between the bridge joints will occur too much displacement, and thus become the direct cause of damage caused by the bridge, so you need to support the width is not particularly large expansion joints set a suitable limit Device, used to limit the relative displacement between expansion joints. In this paper, the limit device design methods were studied, so as to achieve the purpose of its limit.
