摘　　要：隧道在偏压作用下,严重者会产生开裂、局部偏压或整体偏移。从监控量测出发,结合谷(城)竹(溪)高速公路白鹤隧道的实际情况,对偏压段典型断面zk91+335的变形特点、变形演变过程进行了分析,并利用回归分析方法,对该断面进行了稳定性判断,有助于隧道后续施工。During the unsymmetrical tunnel loading, it can produce cracking, partial migration or migration. This article focused monitoring measurements , combined from gucheng to zhuxi highway of the actual situation of the baihe tunnel, analyzed the typical section zk91＋335 and its the deformation characteristics, evolution process, and the regression analysis method, the cross section of a judgment of stability, it contributed to subsequent construction of tunnel.
