天津新港地区高桩码头,目前主要是宽桩台结构,这是与现有施工机具和设备相适应的,但它有一些缺点,需要改进。 新港地区近年来所建的深水高桩码头,高桩台加后板桩档土墙的结构型式(图1),需使板桩有足够的深度,以保持码头的整体稳定。其中后方桩台为预应力简支梁板结构,桩距3.5×7米。前方桩台,桩的排距为
The high-pile wharf in Tianjin’s Xingang area is currently mainly a wide-tailed platform structure, which is compatible with the existing construction machinery and equipment.
