城市明挖隧道抗浮设计思考与研究

Thinking and Research on Anti-floating Design of Urban Open-excavated Tunnel

随着城市土地资源的集约型发展,为缓解城市交通压力,在城市地面向上发展受约束和考虑周边环境景观要求的背景下,城市下沉式隧道越来越多地应用于交叉口相交或道路主线下穿工程中。结合近些年广东地区明挖隧道设计经验,对明挖隧道的抗浮设计进行思考和研究,为其他类似工程实践提供有益参考和借鉴。

With the intensive development of urban land resources,in order to alleviate the urban traffic pressure,the urban subsidence tunnel is more and more used in the road intersection or the under-crossing of the main road under the background of restricting the urban ground upward development and considering the surrounding environmental landscape requirements.Based on the design experience of open-excavated tunnels in Guangdong in recent years,the anti-floating design of open-excavated tunnel is thought and studied,which provides a useful reference for the other similar engineering practices.
