一、概况Ruck-A-chucky 桥是美国林同炎国际汉森工程公司设计的。该桥跨越加州奥本地方的一座水库,单跨1300英尺。由于水库中间水深450英尺,给桥墩施工造成困难,而且深水中的水下地震力很大,也不宜设置桥墩。水库两岸的公路已与山脚岩面相切,如果修建一座正桥,则桥头引道的弯道势必开挖大量石方和导致坡脚失稳,从而浪费巨额投资。同时要求在施工中尽量减少对自然环境和景观的破坏。因此该桥设计成钢索锚固在峡谷两岸
First, the overview Ruck-A-chucky bridge is the United States Lam Lam International Hansen engineering company design. The bridge spans a reservoir in Auburn, California, spanning 1,300 feet. Due to the water depth of 450 feet in the middle of the reservoir, it is difficult to construct the piers, and the underwater seismic force in deep water is very large. The roads on both banks of the reservoir have been tangent to the surface of the foot of the foot. If a right bridge is constructed, the corners of the bridge approach road will inevitably excavate a large number of stones and lead to the slope foot instability, thus wasting huge investment. At the same time, it is required to minimize the damage to the natural environment and landscape during construction. Therefore, the bridge is designed to anchor cables to both sides of the Canyon
