随着交通运输业的快速发展,一些大型的桥梁也逐渐增多,与此同时,船舶吨位日益增大,航行的速度向着高速化方向发展,通过航道的船舶数量越来越多,在外部环境影响的情况下,会出现船舶撞击桥梁的事件。桥梁撞击以及对其的防护问题引起了社会各界的广泛关注。解决桥梁的撞击问题,就需要对其撞击数值进行分析,以此来建立具有防护装置的船桥撞击模型,对桥梁基础防护进行设计,做好桥梁的防护工作。本文就撞击数值模拟下的公路桥梁基础设计问题进行研究。
With the rapid development of the transportation industry, some large bridges are gradually increasing. At the same time, the tonnage of ships is increasing day by day. The speed of navigation is developing toward the speeding. The number of ships passing through the fairways is increasing. , There will be a collision of the ship with the bridge. The impact of the bridge and its protection has aroused widespread concern in the community. To solve the impact of the bridge, it is necessary to analyze the impact value, in order to establish a ship bridge impact model with protective devices, to design the bridge foundation protection, to do a good job of the bridge protection work. In this paper, the impact of numerical simulation of road and bridge under the basic design issues.
