阿尔及利亚东西高速公路某标段泥灰岩、泥灰质粘土地段,岩土体受自然环境的影响,具有易风化、膨胀性、水敏感性等工程特性,通车后出现边坡溜坍、滑坡、锚杆墙变形等路基病害,研究其工程治理措施至关重要。该文根据病害的类型和特点,通过监测和处理方案的试验研究,分析了病害形成的原因,探讨其产生的机理,提出了整治措施。浅层边坡失稳采用放缓边坡、重力罩面、支撑渗沟和骨架护坡,锚杆墙变形采用长锚杆加固、平台防水、坡面排水等综合措施,具有良好的效果。
Algerian east and west highway section of a marl marl, marly clay, rock and soil by the natural environment, with easy weathering, expansibility, water sensitivity and other engineering features, after the opening slipped slope, landslide, anchor Rod wall deformation and other roadbed disease, research project management measures is essential. According to the type and characteristics of the disease, through the experimental research on monitoring and treatment programs, the causes of disease formation were analyzed, the mechanism of its occurrence was discussed, and the remediation measures were put forward. The instability of shallow slope adopts the comprehensive measures such as slow slope, gravity cover, supporting seepage ditch and skeleton slope protection, long bolt deformation, waterproof platform and slope drainage, which has good effect.
