在公路桥梁水毁中，有不少是因为基础理深不够所致，如能对钱基桥墩进行局部冲刷防护加固，则可以避免或减少水毁，故此需预测桥墩局部冲刷深度和范围。1990年作者在西安公路学院水力实验室对陕西省石泉汉江大桥的防护进行了专项试验，对桥墩局部冲刷深度计算和冲刷防护的研究成果进行了试验与完善。 In the road and bridge water damage, many of them are due to the lack of basic rationality. If partial scouring and reinforcement of Qianji pier can avoid or reduce water damage, it is necessary to predict the depth and scope of partial scouring of pier. In 1990, the author carried out a special test on the protection of the Han River Bridge at Shiquan in Shaanxi Province in the Hydraulic Laboratory of Xi’an Highway College. The research results on the calculation of the partial scour depth and the scour protection of the pier were tested and perfected.
