摘　　要：根据地质雷达测试隧道围岩松动圈的原理,提出了测试方案,并在共和隧道进行了实测,得出地质偏压隧道围岩松动圈的分布变化规律。结合层状围岩破坏规律和板裂结构理论,得出地质偏压隧道围岩破坏模式和初衬开裂的原因,据此提出相应的治理措施。According to the principle of measuring the broken rock zone （BRZ） with GPR, the method of the measuring of the broken rock zone was proposed. According to the measuring of Gonghe-tunnel, the law of the distribution and vary of broken rock zone of unsymmetrical-tunnel in geologic were obtained. Based on the law of failure of layered rock and the theory of slab-rent structure, the failure model of the rock of unsymmetrical-tunnel in geologic and the reason of the failure of liner were worked out and the treating measurement was proposed.
