摘要
为减少南北向行人、自行车对东西向机动车的干扰,改善长安街的交通状况,北京市政府决定沿长安街修建数十条地下过街道,并把它列为1994年重点工程之一.由铁道部隧道工程局承建的十条过街道工程(南池子至复兴门)应用新奥法原理设计,采用浅埋暗挖法施工.该工程具有施工环境特殊、结构跨度大(结构净跨10.0m、开挖跨度11.6m)、埋深浅(结构上覆土层厚0.6m～1.0m)、小矢跨比(矢跨比仅为0.13),路面活载作用频繁和土质差等显著特点.本文主要介绍工程的设计、施工和监控量测等方面的内容.
In order to improve the traffic condition of Chang An Jie by reducing the interference of north south bike and pedestrian movement with east west mobile trafic, the Beijing Municipal Goverment decided to build dozens of underpasses and listed them as one of the three key projects of the city in 1994. The ten underpasses undertaken by the Tunnel Engineering Bureau of the Ministry of Railway were designed and built according to the New Austrian Tunnelling Method with extraordinary shallow overburden. This project has wide span ( with a clear width of 10 m., an excavation width of 11.6 m. ); shallow overburden (0.6-1.0 m. ); very frequent live loading and poor soil condition. This paper gives an introduction of the design, construction and monitoring of the project.
