摘要
结合某膨胀性围岩隧道衬砌结构病害分布特征,对典型膨胀性围岩隧道衬砌结构进行了质量检测和承载力分析,并结合衬砌结构稳定性监测规律、检测结果进行结构计算,从质量缺陷、结构承载力、变形稳定性3个方面进行深入分析,最后对隧道结构安全进行了综合性评价。
Combined with the distribution characteristics of the tunnel lining structure of an expansive surrounding rock, the quality inspection and bearing capacity analysis of the typical expanded surrounding rock tunnel lining structure are carried out. And the stability of the lining structure monitoring law and the test results is combined to carry out structural calculations. From the quality defects, structural bearing capacity, deformation stability of three aspects of in-depth analysis. Finally,gives a comprehensive evaluation on the safety of the tunnel structure.
