Urban Underground Railroad arch tunnel Construction Technology Group
Abstract Project in Guangzhou Metro Line, right-arch construction method of tunnels to explore. Subway Construction in Guangzhou for the first time put forward a double-arch tunnel to single-hole tunnel construction technology, and a single type of wall and split in the wall structure, comparison and selection of Technology solutions were obtained to meet the structural safety, construction safety and Economic benefits of better Technology solutions for the future design and construction of similar projects to provide reference and reference.
Keywords: double-arch tunnel group; a single type of wall; construction Technology; split in the wall.
As the circuit design requirements subway tunnel, the tunnel structure produces a variety of forms, ranging from cross-section from double-arch and the three-arch tunnel composed of double-arch tunnel section is commonly used in the connection lines and crossing lines. In this paper, engineering examples, according to tunnel in which geological conditions, duration requirements, raised through the comparison and selection can achieve rapid construction and the purpose of construction cost savings of the best construction programs.
1 Project Overview
Guangzhou Metro Line Road station turn-back line of sports for sports Road station after the return line, structure complex, DK3 016.047 ~ 037.157 varying cross-section set the double-arch structure, three-arch structure of tunnels. Ranging from cross-arch tunnel excavation span 20.1m, excavation height of 10.076m, cross-vector ratio of 1:0.5, after lining a hole span 5.2m, large holes, after lining span 11.4m, the wall thickness of 1.6 m. Three double-arch tunnel excavation span 19.9m, excavation height of 7.885m, cross-vector ratio of 1:0.1. -Arch tunnel section of rock from top to bottom are: artificial fill soil, red - alluvial sand, alluvial - alluvial soil, river and lake facies s
