一、前言 壅水计算是桥渡设计的一项重要内容,也是市政交通部门和企业生产单位所密切关注的对象。随着生产技术的不断发展和科学研究的逐步深入,人们越来越清楚地认识到合理控制壅水的重要意义,力图取得更为精确的计算结果。只是由于桥下水流现象过于复杂,在这方面所取得的成就并不十分理想。 First, the preamble Xiu water calculation is an important part of the design of the bridge crossing, but also the municipal transportation departments and production units pay close attention to the object. With the continuous development of production technology and the gradual deepening of scientific research, people realize more and more clearly the importance of controlling sluice water rationally and strive to obtain more accurate calculation results. It is only because of the complicated flow of water under the bridge that the achievements made in this respect are not very satisfactory.
