通过对浅埋小净距隧道围岩压力的计算进行分析，得出隧道围岩压力的计算公式。以白山大断面小净距隧道为例，采用荷载结构法对隧道衬砌进行了检算，得出衬砌安全系数，并与规范值进行对比，以此评定隧道衬砌设计的合理性，对大断面浅埋小净距隧道的设计有一定的指导意义。
通過對淺埋小淨距隧道圍巖壓力的計算進行分析，得齣隧道圍巖壓力的計算公式。以白山大斷麵小淨距隧道為例，採用荷載結構法對隧道襯砌進行瞭檢算，得齣襯砌安全繫數，併與規範值進行對比，以此評定隧道襯砌設計的閤理性，對大斷麵淺埋小淨距隧道的設計有一定的指導意義。

In this paper,it conduct the analysis calculation of rock pressure in shallow neighbor-hood tunnel,and obtain the the formula of rock pressure.Based on large section with small spacing tunnel in Baishan,the tunnel lining structure were seized count by the load method,and draw the safety factor of lining,which is compared with the specification values,thereby assessing the reasonableness of design of the tunnel lining.It has some significance for design of the large section with shallow buried Neighborhood tunnel.
