摘要
某隧道施工中采用TSP技术进行超前地质预报,从开挖过程来看,洞身围岩揭示隧道超前地质预报结论符合现场施工实际情况。根据超前地质预报结论,结合掌子面实际开挖情况,随时调整开挖进尺,采取必要措施,保证了隧道的安全、优质贯通。
TSP technique is used in a tunnel construction project to implement advance geological forecast. During excavation process, the wall rock of tunnel body indicates the advance geological forecast conclusion accords with the practical situation of construction field. According to the advance geological forecast conclusion and combining with the practical excavation at operating platform, the excavation footage is adjusted momentarily, necessary measures are adopted, thus the safety and high quality of tunnel excavation is ensured.
