公路建筑物主要是运输建筑物,但是,一旦受到了水流的作用,如跨越河流的桥梁和与河道并行的公路等,又具有水工建筑物的性质而遭遇到很多水力问题。公路建筑物遭到的水力问题,可分为两类:一类是水毁,系因洪水和雨水造成的各种不同程度破坏;另一类是水害,系因洪水淹没等而带来的经济损失。
Road buildings are mainly transport buildings, however, they encounter many hydraulic problems once they are subjected to the effects of currents, such as bridges across rivers and roads running parallel to rivers, which have the properties of hydraulic structures. Hydraulic problems encountered by road structures can be divided into two types: one is water damage, which is caused by various degrees of damage caused by floods and rainwater; the other is water damage caused by floods, etc. loss.
