七十年代初,在美国休斯敦航道上兴建了一座长200米、高20米的大型锚定钢板桩岸壁。事先虽曾进行了详细的工程地质勘察,并由一位对水工建筑物有20余年设计经验的注册土木工程师设计,但建成后仅半年时间就因岸壁侧向位移和转动过大而不得不报废、重建。 岸壁工程概况 如附图所示,钢板桩岸壁顶面高程+7.0米。航道底面高程-13米,以22°缓坡在高程-5.5米处与岸壁面相接。钢板桩入土深度12米。在岸壁后方17米处打一
In the early 1970s, a large anchored steel sheet pile wall 200 meters long and 20 meters high was constructed on the Houston Waterway in the United States. Although a prior engineering geology survey was conducted in detail and was designed by a registered civil engineer with more than 20 years of design experience in hydraulic structures, only half a year after construction was forced to displace and rotate sideways due to excessive lateral displacement Scrapped, rebuilt Shore wall project profile As shown in the figure, the top of sheet pile wall elevation +7.0 meters. Elevation of the bottom of the waterway is -13 meters, with a gentle slope of 22 ° at an elevation of -5.5 meters and meets the shore wall. Sheet pile soil depth of 12 meters. Beat 17 meters behind the shore
