摘　　要：鉴于地形偏压小净距隧道的特点,研究围岩稳定性的影响因素。以石家庄至冀晋界曹家庄公路曹家庄小净距隧道为研究背景依托,针对地形偏压高速公路小净距隧道制定了一套有效的安全监测方案,施工现场根据方案进行了有效的监控量测,保障了小净距安全施工,为类似工程做参考。In view of the characteristics of small-interval tunnels with terrain bias, the lntJuencmg factors o2surrounding rock stability are studied. Based on Caojiazhuang small-interval tunnels at Shijiazhuang-Caojiazhuang Highway at the boundary between Hebei and Shanxi, aiming at the small-interval tunnels ofterrain bias highway, we have developed a set of effective safety monitoring scheme, carried out effectivemonitoring measurement at the construction site according to the scheme, guaranteed the of constructionsafety of small intervals, which can serve as a reference for similar projects.
