TSP超前预报法在秦安高风险隧道中的应用
|
摘要
为确保高风险隧道施工安全,如塌方、突水等安全事故的发生,采用超前预报避免地质灾害发生,保障隧道中不良地质段的安全施工显得尤为重要。结合宝兰客运专线秦安隧道工程,综合掌子面地质编录资料和TSP超前地质预报系统探测资料,解译探测资料时以地质编录资料为基础,以P波深度偏移剖面、提取的反射层和岩性参数图等P波数据资料为主,结合S波在液体中传播的特性综合判断,成功地预报了掌子面前方的断层(碎裂带)、软岩和地下水。通过预测结论和实际开挖情况相对比,分析了该方法的适应性及其特点,为隧道施工期超前预报中类似工程预报方法的选用具有一定的参考价值。
Adopting advanced prediction to avoid geological disasters,such as tunnel collapse,water burst and so on,it's particularly important to make sure bad geological section construction safely in high-risk tunnel. Combining geological resource of tunnel face and detection data of TSP advanced geological prediction system,interpreting the detection data,which should be based on the geological resource,in order to get results exactly give priority to taking into account P-wave data such as P-wave depth migration,reflector extraction diagram and lithologic paramete and the properties of S-wave propagate in the water etc,the fault crushed zones,soft rock and underground water in the front of tunnel face were successfully predicted. Contrasting prediction results and the actual excavation situation,the adaptability of this method and its characteristics were analyzed,and provide certain reference value for similar project of advanced prediction in tunnel construction.
