摘　　要：随着社会进步,国家经济发展需要,高速公路作为经济发展的必要纽带,让城市之间的联系更加紧密。在经济下行,房地产行业不景气情况下,高速公路等基础设施投资作为拉动国家经济的必要措施显得越来越重要。当下高速公路设计标准不断提高,对路线的纵坡和平面曲线半径提出了更高的要求,公路线路技术水平提高势在必行。为满足平纵技术指标,隧道在公路中越发常见,尤其是在山岭地段,隧道占比较大。地下隧道在穿越复杂地质情况低端,时有发生坍塌事故,处治不好极易触发安全事故,造成更大的损失。本文通过实践总结出切实有效应对复杂地质情况下的洞内大管棚施工技术,以便在同类施工中借鉴,提高公路隧道施工技术。With the progress of society and the needs of national economic development,highways,as a necessary link for economic development,make the connections between cities closer.In the context of economic downturn and sluggish real estate industry,investment in infrastructure such as highways is becoming increasingly important as a necessary measure to drive the national economy.With the continuous improvement of highway design standards,higher requirements have been put forward for the longitudinal slope and plane curve radius of the route.It is imperative to improve the technical level of highway routes.To meet the horizontal and vertical technical indicators,tunnels are becoming increasingly common in highways,especially in mountainous areas where tunnels account for a large proportion.When underground tunnels pass through complex geological conditions at the lower end,collapse accidents may occur from time to time.Improper treatment can easily trigger safety accidents and cause greater losses.This article summarizes practical and effective construction techniques for large pipe sheds in tunnels to cope with complex geological conditions,in order to learn from and improve the construction technology of highway tunnels in similar constructions.
