中文摘要：
以奉（节）巫（溪）高速公路孙家崖隧道为工程依托，探讨隧道穿越滑坡体时隧道施工对滑坡体的影响机制与处治技术。在滑坡形成机理与变性特征分析的基础上，基于理论研究和数值分析方法提出针对性的滑坡体综合防治措施设计；采用多方位的监控量测措施全程监控了隧道开挖施工扰动对滑坡体形变的影响，并由此探讨隧道与滑坡体之间的相互作用机制。研究结果表明：滑坡体抗滑桩处治方案减小了隧道开挖对滑坡体稳定性产生的不利影响；隧道支护措施能同抗滑桩支挡结构一起组成组合抗滑结构体，有利于滑坡体的稳定。
英文摘要：
Based on the Sunjiaya tunnel of Fengwu expressway, the treatment technology and influence mecha- nism of landslides were investigated during the tunnel constructions. According to the form mechanism of land- slide and analysis of deformation characteristics, the comprehensive prevention measurement design of landslide mass was proposed based on theoretical research and numerical analytical method. The effect of tunnel construc- tions on the landslide deformation was observed by various monitoring measurements. Thereby, the interaction mechanism between the tunnel and landslide mass was studied. The results show that the anti -slide treatment technology of landslide mass reduces the adverse effect of tunnel excavation on the stability of landslide mass. The combination of tunnel support measurements and anti - slide piles in the tunnel constructions would be con- sidered as the anti -slide structure composition, which is conductive to the stability of landslide mass.
