【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。更多还原

【Abstract】 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 slabrent 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.更多还原
