摘要
结合蒙西至华中地区铁路煤运通道工程银山2号隧道具体工程特点,针对黄土隧道的特性,采取切实可行的支护参数和施工工艺,探讨施工过程中控制沉降变形的措施,从而达到施工工程中控制地表及拱顶沉降的目的。
Combining the specific engineering characteristics of Yinshan No.2 tunnel with the railway coal transportation channel project from Mengxi to Central China, according to the characteristics of the loess tunnel, practical support parameters and construction techniques are adopted to discuss measures to control settlement and deformation during construction, in order to control ground and vault settlement during construction.
