摘要

摘要: 全遮帘式板桩码头作为一种新型结构,为板桩码头向深水化发展提供了可能。全遮帘式码头的设计尚无完备理论,遮帘桩排列的间距一般多依据工程经验确定,尚无成熟的计算方法。遮帘桩属于典型的被动桩,一定条件下遮帘桩后形成土拱效应,使得桩后大部分土压力由土拱传递给遮帘桩,从而改善了前墙的受力情况。基于遮帘桩后土拱效应存在的假定,联合桩间静力平衡条件、土拱跨中截面强度条件和拱脚三角受压区破坏条件,确定了遮帘桩间距的计算公式。

Abstract: The all-covered type of sheet-pile wharf is a new type structure, which makes the sheet wharf possibly be used in the construction of deep water berth. There is still no complete theory for the design of the all-covered type of sheet-pile wharf, and the spacing of barrier piles is mostly determined by engineering experience, as there is a lack of any mature method. The barrier pile is a typical passive pile. The soil arching behind the barrier piles will be formed under a certain condition. Most of the soil pressure behind the piles is transferred to the barrier piles by the soil arching, and thereby the mechanical behaviors of the front wall can be improved. Based on the assumption that soil arching effect exists behind the piles, combined with the static equilibrium equation, strength condition for mid-span section of the soil arching, and the failure condition for the triangle compression zone at the arch springing, a formula for the spacing of barrier piles is proposed.
