摘要
作为一名桥梁设计者,可以在设计部分预应力构件、改进主梁截面、采用高强材料及选择合适的预制方法等四个 方面优化设计,提高简支空心板桥的经济跨径。
As a bridge designer, you would optimize design in the four sides. They are the pre-stress beams in design, upswing the main beam section, use the high strength material and choose the equal pre-stress method, they would raise the economic stride with the simple blank-line board.
