基于HSP声波反射法的隧道超前地质预报

摘要

文章在对HSP声波反射法的工作原理、仪器设备及测试分析软件介绍的基础上,结合SZ隧道出口段掌子面的实际地质条件,对其出口左右线掌子面进行测试分析,并得到施工开挖验证.应用HSP声波反射法对隧道掌子面前方地质条件进行及时准确的预测,提前采取预防措施,避免灾害的发生,或在一定程度上减少因灾害造成的损失,减少施工过程的干扰,对隧道的安全施工具有积极的指导作用,值得在同类隧道施工地质预报中推广应用.%Based on the introduetion of working principles, instrument, equipment and analysis software of the Horizontal Sound Probing method and considering the geological conditions of the area involved, authors of the paper tested and analyzed the SZ tunnel face on exit section, the results were verified by excavation. Application of HSP to timely and accurately forecast geological conditions in front of the tunnel face helps to take preventive measures to avoid disasters or to reduce the losses caused by disasters, which can guide the safety tunnel construction and would be worthy of disseminating and applying for similar tunnel geological forecasting .
