城市交通隧道的建设过程中不可避免地遇到工程建设与环境保护的矛盾。该文以穿越生态园区的普瑞隧道的建设为背景,探讨了建设空间狭小、建设条件苛刻、地质条件差、环境保护要求高的条件下,城市交通隧道的方案论证过程和设计思路。通过分析计算,得到了普瑞隧道深大异形基坑的支护方案和大跨度明洞隧道结构的修建方案,确保了工程安全、先进和环保。
Urban traffic tunnel construction process inevitably encountered the contradiction between construction and environmental protection. Based on the construction of Purui Tunnel which crosses the ecological park, this paper discusses the process and design of the scheme of urban traffic tunnel under the condition of small construction space, harsh construction conditions, poor geological conditions and high environmental protection requirements. Through the analysis and calculation, the construction plan of large-scale special-shaped foundation pit in Purui Tunnel and the construction of long-span tunnel structure in Myeong-dong are obtained, ensuring the safety, advanced and environmental protection of the project.
