| 摘 要： | 通过检测发现云南富广高速公路部分隧道因施工控制问题引起的缺陷主要有：二次衬砌厚度不足、二次衬砌与初期支护之间存在空洞、砼表面存在纵向裂缝等，分析了缺陷产生的原因，并介绍了相应的整治方案，如湿喷C25微纤维混凝土、挂钢筋网、加设锚钉和w钢带补强的方法等。实践证明，这些方法使用范围广，能满足不同的加固要求，是在通车情况下对隧道进行整治的有效措施。

| Abstract: | It has been found that the defects resulting from the poor construction control in part of the tunnels of the Yunnan Fu-Guang Expressway consist chiefly of insufficient depth of secondary lining,cavities between the secondary lined layer and the initial supporting layer,and the longitudinal cracks in the surface of concrete,the various causes of which are analysed in the paper,with corresponding remedies presented,such as wet-slip-casting C25 microfibre concrete,laying reinforcing nets,providing additional ... |
