盾构区间过站技术研究

Analysis on Shield Station-passing Construction Technology

摘要:

城市地铁广泛采用盾构施工，目前城市盾构区间施工一般具有工程量小、里程短、盾构过站多、盾构调头多等特点，盾构过站是其重要组成部分。盾构过站一般场地狭小、工序繁多，合理的盾构过站，既可节省人力物力，又能保证优质高效地完成工程。结合工程实际，对盾构过站技术进行了较深入的研究。

Abstract:

Shield construction is widely used in the urban metro; the urban metro generally has the characteristics such as small engineering quantity, short mileage, multi stations and a large number of turning around, etc. Station-passing plays an important role in the construction. Shield generally has a narrow space and various processes, so the reasonable shield station-passing can not only save manpower and material resource, but also can ensure the engineering quality. Based on the engineering practice, the shield station-passing construction technology has been deeply studied in this paper.
