【Abstract】 Ground pressure of tunnel is an extremely complicated problem concerned with many factors. In this paper, based on the in-situ measurement in two loess tunnels, the magnitude and distribution form of gorund pressure are analyzed and compared with the existing calculation result. Besides, the definition of shallow and deep tunnel, second lining and invert are expounded.更多还原
