摘要
通过室内水槽试验对桥墩施工期沉井下沉过程中的流态及流速变化进行了探讨。分析了沉井附近流速与行近流速、沉井下沉入水深度的关系。此外,通过对实测资料的分析,得到了沉井下沉过程中沉井附近流速分布的变化以及行近流速对冲刷坑影响的规律。
Based on the information obtained from flume experiments, the velocity variations in the process of open caissons descending were studied. The relationships between the velocity around open caissons and the flow velocity, the depth of open caissons entering water were analyzed. Besides, based on the analysis of the experimental data, the variation of the velocity profiles around open caissons and the law of the effect of the flow velocity on scour holes were obtained.
