摘　　要：以中国企业在欧洲修建的第一条高速公路项目——黑山某高速公路项目隧道工程为背景,依据中东欧地区技术规范要求,结合该区域工程地质、水文资料及滑动面分布情况,从地质情况、水文情况和施工影响等三个方面,分析隧道口滑动面产生的原因及其对隧道施工和安全产生的影响;进行稳定性分析,根据滑动面特征和分布情况,采用综合措施进行治理,确保山体稳定和隧道结构安全。通过监测数据证明,采取的综合整治措施可靠和安全有效。Based on the background of the Mate?evo tunnel project of the Bar—Boljare expressway project in Montenegro, the first expressway project built by a Chinese enterprise in Europe, according to the technical specifications of central and eastern Europe, combined with the engineering geology, hydrological data and slip surface distribution of the region, from three aspects of geology, hydrology and construction impact, the causes of tunnel portal sliding surface and the impact to tunnel construction and safety has been analyzed, and the stability analysis has also been carried out. Comprehensive control measures have been adopted in accordance with the characteristics and distribution of sliding plane to ensure the safety of the mountain stability and tunnel structure with the monitoring data proving that the comprehensive control measures taken are reliable, safe and effective.
