| 中文摘要: |
| 隧道洞口段是隧道施工的薄弱环节，为保证进洞安全，采用地表砂浆锚杆加固拱顶岩体；采用钢拱架、超前锚杆、超前小导管、钢筋网、喷射混凝土联合支护加固洞口岩体；采用控制爆破手段降低对围岩扰动，利用围岩量测技术指导施工。保证了洞口浅埋段的施工安全。 |
| 英文摘要: |
| The tunnel outlet section is a weakness in tunnel construction,in order to ensure the construction safety, the rock mass in arch top is reinforced by grouted rockboh, the rock mass in tunnel outlet is reinforced by steel arch, ahead bolts,ahead pipe, reinforcement mesh and shotcrete, the controlling blasting method is used to decrease the disturbance to rock mass,The surrounding rock is monitored for the safe construction of shallow section in tunnel outlet. |
