【摘要】：在城市地區(qū),新的隧道的開發(fā)必然涉及周邊現(xiàn)有的地下結(jié)構(gòu)。在這種情況下,穩(wěn)定地層附近的現(xiàn)有地下結(jié)構(gòu)可以放寬對(duì)一個(gè)新的隧道開挖的限制。本文以青島地鐵2號(hào)線下穿3號(hào)線小凈距疊交隧道的設(shè)計(jì)與施工為工程背景,針對(duì)青島市城區(qū)地層的水文地質(zhì)條件,從施工部署方面、施工方案方面、支護(hù)技術(shù)方面對(duì)城市超小凈距隧道立體交叉下穿斜隧道的施工進(jìn)行優(yōu)化設(shè)計(jì),并對(duì)爆破過程中的振動(dòng)以及施工所引起的周邊結(jié)構(gòu)的沉降變形進(jìn)行監(jiān)測(cè),結(jié)果表明,通過優(yōu)化施工方案,大大降低了施工對(duì)周邊其他結(jié)構(gòu)的不利影響,為青島地鐵交疊線路的設(shè)計(jì)與施工建設(shè)提供理論指導(dǎo),并為同類地下工程提供借鑒意義。
[Abstract]:In urban areas, the development of new tunnels must involve existing underground structures around them. In this case, the existing underground structure near the stabilized stratum can relax the restrictions on the excavation of a new tunnel. This paper takes the design and construction of the small clear distance overpass tunnel of Qingdao Metro Line 2 through Line 3 as the engineering background, aiming at the hydrogeological conditions of the strata in the urban area of Qingdao, from the aspects of construction arrangement and construction scheme. In the aspect of supporting technology, the optimum design of the construction of the tunnel crossing the oblique tunnel is carried out, and the vibration during the blasting process and the settlement deformation of the surrounding structure caused by the construction are monitored. The results show that, By optimizing the construction scheme, the adverse effects of construction on other surrounding structures are greatly reduced, which provides theoretical guidance for the design and construction of overlapping lines of Qingdao Metro, and provides reference significance for similar underground projects.
