中文摘要:
      为提高跨黏滑断层隧道的结构安全性和稳定性,以都汶高速友谊隧道F1黏滑断层段为研究背景,通过采用纤维混凝土衬砌对跨黏滑断层隧道抗错断技术进行研究。结果表明:同体积纤维掺量条件下,混杂纤维混凝土(SBFRC)立方体抗压强度比纤维混凝土(SFRC)略低,SBFRC抗折强度比SFRC略高;断层黏滑错动对隧道上盘的影响大于下盘;纤维混凝土衬砌对下盘隧道结构的抗错效果优于上盘隧道,SFRC二衬平均抗错效果为12.22%,SBFRC二衬平均抗错效果为15.81%。研究成果可为黏滑断层隧道的结构设计及施工提供参考。
英文摘要:
      To improve the safety and stability of tunnels crossing stick-slip faults, we used fiber-reinforced concrete lining to research the technology of fault dislocation resistance for tunnels crossing stick-slip faults, based on the stick-slip fault F1 crossing the Youyi tunnel of the Duwen highway. Results showed that, under the same volume of fiber content, the compressive strength of SBFRC cube was slightly lower than that of SFRC, although the flexural strength of SBFRC was slightly higher than that of SFRC. The effect of stick-slip fault dislocation on hanging wall was larger than that on footwall. The effect of fiber-reinforced concrete lining on the dislocation resistance of the tunnel structure of footwall was better than that on hanging wall. Average dislocation resistance effect of the SFRC secondary lining was 12.22%, and 15.81% for the SBFRC secondary lining. These results can provide a reference for the structural design and construction of tunnels crossing stick-slip faults.
