一、前言1964年中国土木工程学会“桥渡冲刷计算学术会议”推荐64-2公式为计算桥梁一般冲刷深度的生产试用公式。此后,该式被编入公路、铁路设计手册,载入《公路桥位勘测设计规程》JTJ062—82(试行)。本文介绍最近修订该“规程”进行专题研究的结果,这项结果已
I. Introduction In 1964, China Society of Civil Engineers, “Bridge Crossing Scouring Calculation Conference” recommended 64-2 formula for the calculation of the bridge general erosion depth production trial formula. Since then, the formula has been incorporated into the highway and railway design manuals and is loaded into JTJ062-82 (Trial Implementation) of “Highway Bridge Survey Design Code”. This article presents the results of the thematic study that recently revised the Code and this result is already available
