浅谈黏土地层中的盾构施工技术

DISCUSSION ON SHIELD CONSTRUCTION TECHNOLOGY IN CLAY STRATA

盾构机在黏土地层中掘进施工会遇到较多困难,本文以武汉地铁8号线二期工程马房山站~洪山区政府站区间施工为例,从盾构机选型与设计、螺旋机改造、掘进参数控制、渣土改良等方面介绍黏土地层盾构施工的一些相关技术,为类似工程施工提供参考。

The shield machine tunneling construction in clay strata encountered many difficulties,this paper gives an example of construction in section of Wuhan metro line 8 second stage project between Mafangshan station and Hongshan district government station,introducing the shield machine construction technologies in clay strata from shield machine type selection design,Auger modification,tunneling parameters control and muck improvement,to providing a reference for similar engineering construction.
