摘要
论述了管棚的作用及支护机理。从浅埋地下工程失稳机理入手探讨了管棚的预支护机理和设计参数。引入土拱效应推导出了管棚最大间距设计的计算公式。
With an elaboration of the functions of pipeshed, the pre-support mechanism of pipe-shed is discussed from the angle of the instability mechanism of shallow embedment underground engineering, and the computing formula of the maximum space design of pipe - shed is derived by introducing in the soil-arch effect.
