位于平纵曲线上且有缓和段和超高的渔郎岸大桥 ,为先张法预应力空心板梁 ,空心板从施工工艺和施工设计方面都提出了优化方案 ,如采用水磨石底模、π形门架和以桥跨为通道横移板梁到位等都取得了成功 ,作为桥梁施工新方法、新技术都取得了相应的经济效益。 Located in the flat and vertical curve with the ease section and the ultra-high Yurun shore bridge, pre-tensioned prestressed hollow slab beams, hollow slab from the construction technology and construction design are proposed optimization programs, such as the use of terrazzo bottom mold, π Gantry and bridge span as the channel to move the beam in place and so on have achieved success as a new method of bridge construction, new technologies have achieved the corresponding economic benefits.
