马头山隧道设计方案分析与比选

Analysis and co MParison of design schemes for Matoushan tunnel

单洞对向双车道长大隧道相较于分离式双向双车道隧道,洞内发生事故时由于缺少逃生通道往往会造成更严重的后果。显然双洞方案会付出更高的经济成本,但对于运营安全和缓解交通压力有更大贡献。通过对马头山隧道单洞对向双车道、分离式双洞双向四车道两个设计方案的分析比选,为类似项目设计方案提供参考。

The lack of an escape route in the event of an accident in a double-lane tunnel is often more serious than in a separate double-lane tunnel.Obviously,the double-hole solution will cost more economically,but it will contribute more to operational safety and traffic relief.In this paper,through the analysis and co MParison of the two design schemes of single tunnel to two lanes and separated double tunnel to four lanes,it provides reference for similar projects.
