本报告载有一项研究的结果，该研究旨在制定确定桥墩和上层建筑因水上碎屑而产生的阻力和静水力的实用方法。该报告包括评估这些力量的建议规范。本报告中的材料将直接引起桥梁设计者的兴趣。报告分为四章和一个附录。第一章提供了背景资料，并讨论了研究的目标、任务和范围。第二章总结了碎片对桥梁影响的研究现状。本章还讨论了为确定预测桥墩和上层建筑上的碎片力的方法而进行的实验研究。第三章介绍了碎片力的推荐规范和注释，并将碎片加载规范应用于三个实例。最后一章从研究中得出结论，并提出进一步研究的建议。附录提供了对本研究项目的程序和结果的更详细的说明。
This report contains the findings of a study undertaken to develop practical methods for determining drag and hydrostatic forces on bridge piers and on superstructures due to waterborne debris. The report includes recommended specifications for assessing these forces. The material in this report will be of immediate interest to bridge designers. The report is organized into four chapters and an appendix. The first chapter provides background information and discusses the objectives, tasks, and scope of the study. The second chapter summarizes the state of knowledge on the effect of debris on bridges. The chapter also discusses experimental studies conducted to determine a method for predicting debris forces on piers and on superstructures. The third chapter both introduces the recommended specification and commentary on debris forces and applies the debris-loading specification to three examples. The final chapter draws conclusions from the research and recommends areas for further research. The appendix provides a more detailed account of the procedures and outcomes of this research project.
