| 中文摘要: |
| 石家庄市石中一二线（16# 北道岔站）电缆隧道与阿尔卡迪亚三期商业综合体基坑工程近接，在基坑施工过程中隧道结构出现了开裂现象。采用无损检测、强度试验和数值模拟等手段，对隧道开裂原因进行了分析和探讨，并针对工程特点提出了隧道洞内套拱结合洞周地层注浆的综合治理方案。分析结果表明：在基坑施工过程中，原有隧道结构的安全性已不能满足要求，隧道洞内套拱结合洞周地层注浆的方案，能够保证后续施工和使用安全 |
| 英文摘要: |
| The cable tunnel of Shijiazhuang(16# Beidaocha Station) adjacent to the foundation pit of business combination project of Arcadia community. Based on the means of geophysical prospecting, strength test and numerical simulation, the cracking causes of cable tunnel are analysed. According to the characteristics of the project, the treatment scheme of inner lining inside the tunnel combined with the grouting in surrounding formation is proposed. The results of the research show that the multi purpose treatment scheme can guarantee the safety of the cable tunnel during the follow up construction and operation. |
