【摘要】 结合贵广铁路田坝岭隧道应用实例,介绍了TSP203超前预报系统的实际应用情况,并通过探测推断与实际对比,给出了该系统在地质方面的应用效果及其探测准确性评价。结果表明:从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;参考超前地质预报结论及施工建议,提前采取有效措施,保证了田坝岭隧道进口掌子面的安全施工。更多还原

【Abstract】 Combined with the construction of Tianbaling tunnel in Guiguang Railway,the application of TSP203 system is introduced.By comparing TSP203 prediction and actual condition,the effect and accuracy evaluation of TSP203 are given.The results show that geology forecasting results from surrounding rock is consistent with reality. According to the geology forecasting results and construction suggestion,some effective measures are employed to assure the construction safety of tunnel face in Tianbaling tunnel.更多还原
