| 摘 要： | 在分析了超声回弹综合法测试公路隧道衬砌强度的局限性后,文章提出了应按围岩等级划分隧道衬砌类别,对不同类别的衬砌分别进行强度推定的原则.并提出了应对衬砌声速进行应力修正、考虑龄期和养护环境等因素的新的超声回弹综合测强公式,按该公式推定的抗压强度与芯样试验结果吻合较好.

| Abstract: | The limits of Synthetic method of ultrasonic rebound applied to the strength test of concrete lining of highway tunnel are analyzed,and a principle is put forward that the lining strength should be determined on the basis of the classification of surrounding rock.A new formula is derived after considering the stress in lining,the age and the maintaining condition of concrete.The result obtained from the new formula is in agreement well with the core-drilling test. |
