摘要
运行多年的高速公路,由于沉降等原因,需整修路面通过调整纵坡线形来改善行车的舒适性,但遇到众多桥梁时限制了线形改善程度。本文结合浙江省杭甬高速公路工程实例,介绍如何通过小跨径多梁板桥梁整体同步顶升,较好地解决部分路段的线形调整问题,并取得较明显的经济效果。
Expressways develop the need for profile adjustment by mad resurfacing for improvement in traveling comfort due to settlement after years in operation. The process is hindered when numerous bridges are encountered. This essay discusses the technique of simultaneous raising entire bridge slabs over small intervals to effectively resolve the difficulties related to profile adjustment along certain sections of the Hangzhou - Ningbo Expressway with significant economic benefits through actual case studies.
