摘要 依托某高速公路隧道路面底鼓开裂病害,通过现场试验检测结果来判定隧道底鼓开裂的原因,采用有限元软件模拟病害处隧道仰拱内力,并将病害仰拱与正常仰拱内力进行对比分析,进一步验证病害产生原因,从而为后期加固处治提供准确的数据参考,使加固设计更具针对性。 Based on the cracking disease of a highway tunnel pavement floor heave,the causes of cracking of tunnel floor heave are determined by the results of field test.The internal force of tunnel inverted arch at the diseased site is simulated by finite element software,and the internal force of diseased inverted arch is compared with that of normal inverted arch.The causes of the diseased inverted arch are further verified,so as to provide accurate data reference for later reinforcement treatment.
