摘要
透空式进海路是连接人工岛与陆岸的一种新型结构,其所受波浪力是工程设计中重点关注的问题。本文开展物理模型试验,通过改变水深、波高、桥面底高、桥面宽度等试验条件,研究透空式进海路波浪力的变化规律。试验测量透空式进海路上部结构的动水压强分布,分析得到结构的浮托力和水平波浪力。研究发现:透空式进海路上部结构波浪力的主要影响因素为桥面相对净空高度,在相对净空高度接近0时,桥面浮托力达到最大值。通过分析试验数据,并参照文献中的已有波浪力计算方法,建立透空式进海路上部结构浮托力和水平波浪力的计算公式,公式计算结果与试验结果符合较好,对透空式进海路工程设计具有重要指导意义。
Pile-supported sea access road is a new structure to connect the artificial island and the mainland,and the wave forces on it is the focus for engineering design.In this paper,physical model tests are carried out to studies the wave forces on a pile-supported sea access road by changing the experimental conditions,such as water depth,wave height,bottom height of bridge deck and bridge deck width.The wave pressure distributions on the upper structure of the pile-supported sea access road are measured.Then the uplift force and the horizontal wave force acting on the upper structure are determined.The study finds that the relative clearance height is the main influencing test factor in wave force on the upper structure.The uplift force reaches the maximum value when the relative clearance height is close to 0.Based on the experimental data and previous calculation methods for the wave forces,predictive formulas for the uplift force and the horizontal wave force on the upper structure of the pile-supported sea access road are developed.The calculation results agree well with the experimental data.This study is significant for guiding the engineering design of pile-supported sea access roads.
