摘要
结合上海市迎世博市政道路设施三年整治工作,调查了上海内环线高架匝道桥头段跳车的情况。根据差异沉降量、30m范围内最大间隙值、桥台与搭板搭接处高差等测量数据,分析了内环匝道桥头跳车成因,提出做好搭板处理、纵断面线形调坡处理、桥头路段沥青路面修复等相应整治措施。
Incorporated with the three years' improvement of municipal road facilities for the World Expo in Shanghai, analysis is made of the causes for bumping at ramp abutments, with relevant measures proposed for the remedy, such as better overlapping, adjustment of the alignment slope and recovery of the asphalt pavement at the abutment, based on the investigation therein and data therefrom, such as differential settlement, the maximum crack in the range of 30 m and the difference in height at the overlapping.
