摘要
在现场量测与室内模型试验研究成果的基础上，探讨了用砂浆锚杆对浅埋隧道地表进行预加固的作用效果以及锚杆与地层共同作用的力学机理，由此提出了分析锚杆预加固作用效应的计算方法。计算值与试验结果比较接近。
Based on the results of measuring in site and model test in laboratory, the applying effect that surface of shallow tunnel is pre reinforced with mortar anchored bolts, as well as the mechanics mechanism of bolts and stratum acting on each others, are studied. Then, the calculating method that the applying effectiveness of bolts for pre reinforcing is analyzed,has been given out.The calculated values are very close to the test results.
