【摘要】 盾构工法近年在我国城市隧道中得到快速发展,尤其在城市排污隧道、供水供电、供气等隧道中小断面盾构机得到广泛的应用。而盾构始发乃是盾构的关键技术之一,通过工程实例介绍小断面细长型泥水平衡盾构机在不同地层始发技术,分析比较各种方案的优劣。更多还原

【Abstract】 In recent years, shield-driven method witnesses a rapid progress in urban tunnels in China, especially in urban sewage tunnels, water and power supply tunnels and gas supply tunnels, to which small diameter shields are widely applied. The paper briefly introduces the launching technique, one of the crucial techniques, of the long and thin mud-shields with small diameters in different strata through example projects to analyze and compare the strong points and weak points of different plans for your reference.更多还原
