本文认为岩石河床桥墩局部冲刷是水流冲刷能力与岩石抗冲刷能力相互作用的结果。对现有岩石河床桥梁基础埋置深度的方法进行了简评。分析调查、实测资料发现岩石桥墩局部冲恻最大深度的部位往往在墩上游转折处,对此现象作了初浅分析。在分析调查与实测资料的基础上得到岩石河床桥墩周围局部最大冲刷深度的计算方法。计算值与实测值的验证基本相符。
This paper argues that the partial scouring of the rock-river bed piers is the result of interaction between water scouring ability and rock scouring ability. A brief review of the existing methods for embedding depths of rock riverbed bridges is given. Analysis of the survey, the measured data found that the maximum depth of the local pier rock pier site is often the turning point in the upper reaches of the pier, this phenomenon made a preliminary analysis. Based on the analysis of the survey data and the measured data, the calculation method of the local maximum erosion depth around the bridge piers is obtained. The calculated value is in good agreement with the actual value.
