某地下快速路下穿S20立交方案比选研究

摘要:

漕宝路地下快速路工程下穿S20立交节点,该节点交通流量大,地面环境复杂,在工程建设中需满足地面交通需求并尽量减小环境影响。本文结合工程实际情况,针对下穿S20立交节点,分别提出2种不同的设计方案,并从环境影响、施工难度、工程经济性等多个方面对方案进行综合比选。在选取合适的方案后,针对方案中关键节点分别进行设计,并对方案进行分析,结果表明方案安全可行。工程可为同类型工程设计和研究提供借鉴和指导作用。

Abstract:

Caobao road expressway underground engineering undercrossing S20 node has large traffic flow and complex ground environment. As a result, it is necessary to satisfy the traffic requirement and reduce the environmental effect. In this paper, we put forward two different design schemes for the undercrossing of S20 node, and then compare and select appropriate scheme from the aspects of environmental impact, construction difficulty and engineering economy. After that, the key nodes in the scheme are discussed respectively. The results show that the scheme is safe and feasible, and it can be referred to the similar project.
