高柱码头是长江下游采用较多的一种结构型式,但是,由于长江水位差较大,下游地区一般在5～10米左右,而且停靠船型较多,船舶干舷高度有大有小。为了适应不同水位停靠船舶,码头前方一般都要考虑设置分层带缆,这不仅使码头结构复杂,更主要的是前排桩顶标高较低,使得工期受施工水位影响,施工季节性强,施工期短,不能全年均衡施工。针对这一问题,本文提出一种结构设想,现简述如下:
However, due to the large water level difference in the Yangtze River, the downstream area is generally about 5 to 10 meters, and there are many docked ships, and the freeboards of ships have different heights. In order to adapt to different water level to dock the ship, the front of the wharf should generally consider setting stratified belt cable. This not only complicates the structure of the wharf, but more importantly, the elevation of the roof of the front row is lower, making the construction period influenced by construction water level, Construction period is short, not balanced construction throughout the year. In response to this problem, this paper presents a structural assumption, are summarized as follows:
