摘要
随着工程等级的不断提高,在隧道开挖中遇到的地质环境越来越复杂,隧道地质超前预报在隧道开挖中的作用越来越显著。因此,如何选择有效的预报措施对隧道开挖中人员、设备的安全和隧道硐室的支护方式具有重要意义。主要介绍TGP12型隧道地质预报仪探测系统的原理、数据处理、解释技术和在大坪隧道施工中的超前预报应用。通过对比分析验证了预报结果的准确性,展示了TGP12型隧道地质预报系统在隧道施工地质超前预报中的广阔应用前景。
As project level upgrades, the geological environment encountered during tunnel excavation is getting more and more complicated, and the geological advance forecast for tunnels is getting more and more important in tunnel excavation. Therefore selecting effective forecast measures has important meaning for personnel and equipment safety during tunnel excavation, tunnel supporting and protection, etc.. This paper mainly introduces principle, data processing, explanation technique of TGP12 model tunnel geological predictor detection system and its application in advance forecasting for Daping Tunnel construction. Through comparison and analysis to the accuracy of forecast results, this TGP12 model tunnel geological predictor detection system shows broad application future in advance geological forecast for tunnel construction.
