蓉江四路越江隧道工程设计关键技术

Key Technologies for Design of Rongjiang Fourth Road River-crossing Tunnel Project

摘要:

赣州市蓉江四路越江隧道总体方案设计过程中，对隧道、桥梁方案，从工程层面对工程地质风险、方案可靠性、可实施性和工程经济性等方面进行了比较，按综合效益最优的原则，确定采用暗挖隧道方案，并对越江隧道土建、防水排水、防灾疏散等设计及施工关键技术进行介绍。在地质条件适宜的条件下，蓉江四路越江隧道工程实践证明，采用水下隧道越江是较优及可行的。

Abstract:

In the design process of the overall scheme of Rongjiang Fourth Road River-crossing Tunnel Project in Ganzhou City, the tunnel and bridge schemes are comprehensively compared from the engineering level of engineering geological risks, scheme reliability and practicability, engineering economy, etc. According to the principle of optimum comprehensive benefit, the hidden tunneling scheme is determined. And the key design and construction technologies such as civil construction, waterproofing and drainage, disaster prevention and evacuation of the cross-river tunnel are introduced. The practice of Chengjiang Fourth Road Cross-river Tunnel Project shows that it is better and feasible to use the underwater tunnel to cross the river under the suitable geological conditions.
