一、前言桥墩局部冲刷65-1公式和65-2公式是1964年中国土木工程学会“桥渡冲刷学术讨论会”推荐的生产试用公式。此后两式载入铁路、公路有关规范。多年生产实践表明,两式结构较为合理,基本上反映了冲刷深度与流速间的变化关系,考虑因素较全面,计算结果较为稳定
I. Preface Pier scour 65-1 formula and 65-2 formula is the 1964 China Civil Engineering Society “Bridge crossing scouring Symposium,” the recommended production trial formula. After two types of loading railway, highway related specifications. Years of production practice shows that the two-type structure is more reasonable and basically reflects the relationship between the erosion depth and the flow rate. The factors considered are more comprehensive and the calculation results are more stable
