中文摘要：

通过侧限压缩和三轴压缩试验以及野外调查，分析了裂隙和含水率对裂缝带土压缩性质的影响，总结了地裂缝带路面的4种变形破坏形式，提出了公路地裂缝灾害的避绕、适应和减缓等综合防治措施。试验结果表明：侧限压缩条件下，裂缝带土在0～50kPa和大于200kPa时的压缩性明显大于非裂缝带土；三轴压缩条件下，裂缝带土中裂隙的变形方式有压缩变形、剪切变形、纵向拉张变形、横向拉张变形和旋转变形5种，裂隙的局部变形特征决定了裂缝带土的整体变形方式；同一裂缝带土的强度随着含水率的增大而降低。

英文摘要：

By means of confined compression test, triaxial compression test and field investigation, the compression characteristics influenced by the fissure and moisture content of soil samples were analyzed, 4 deformation and failure types of pavement in ground fissure zone were summarized, and such measures of preventing road hazards as avoidance, adaptation and mitigation were also proposed. The results show that the compressibility of fissured soil samples at the pressure of 0-50 kPa and 〉200 kPa under confined compression condition is significantly greater than that of undisturbed samples, and under triaxial compression condition, there are 5 different fissure deformation modes of compression deformation, shear deformation, longitudinal tensile deformation, lateral tensile deformation and rotation, which determine the overall deformation of fissured samples. The strength of the same type of sample is reduced with the increase of moisture content of soil.
