摘要
结合上海G1501郊环线(东南段)大修工程,在总体投入受控的前提下,以路况调查分析结果为基础,遵循"针对性设计和全寿命设计"与"极限利用,经济节约"的原则,建立在各项路面技术状况指标的基础上,通过既有路面缺陷整治与结构维修,消除原路面病害与结构强度不足,最终通过加罩补强实现路面结构强度的整体提升,同步完善路基路面的防护与排水设计,以满足今后较长时间的使用要求。
This paper introduces the Shanghai G1501 Suburb Ring Line(Southeast Section) Overhaul Project.In the premise of the overall investment control, and based on the survey result of road condition, the principle of 'specific design and whole life design' and 'ultimate utilization and economy' is followed. On the basis of various pavement technical condition indexes, the treatment of the existing pavement faults and the maintenance of structures can eliminate the original pavement faults and the insufficient structural strength,and finally the overlay and reinforcement can realize the overall upgrading of pavement structural strength,and synchronously perfect protection and drainage design of subgrade and pavement in order to meet the longer-time service in the future.
