桥墩周围的局部冲刷是一个有建筑物条件下水流的旋涡系与土质相互作用的结果。许多科技工作者从现场实测资料、模型试验资料建立经验公式;从研究桥墩周围冲刷坑水流结构,力图从理论上建立计算公式。近年来,桥墩周围局部冲刷的理论研究、模型试验及现场实测资料的分析,不同河床质的桥墩局部冲刷计算方法,国内都有新的进展,新的计算方法。
The local scour around the piers is the result of the interaction of the vortex system with soil under the conditions of the building. Many scientists and technologists establish empirical formulas based on measured data and model test data from the field; scour the pit flow structure around the piers and try hard to establish the formula theoretically. In recent years, the theoretical research of local scour around bridge piers, the model tests and field measurement data analysis, the different scouring piers local scouring calculation method, there are new developments and new calculation methods.
