【摘要】 近年来,隧道超前地质预报得到了快速发展,并在隧道施工中发挥了重要作用。目前隧道超前地质预报方法种类很多,但普遍存在预报距离和准确率不能兼顾的问题,并且现场测试较为复杂。针对上述方面的问题,水平声波剖面法(HSP)可通过其测试布置方法和数据处理技术较好的解决。文章简述了HSP原理、测试针对方法及关键技术,并在典型工程应用实例的基础上,总结分析了HSP应用效果和技术特性。更多还原

【Abstract】 Advance geological forecast technology for tunnels has been growing quickly in recent years and now plays a key role in tunnelconstruction.Although there are many advance geological forecast methods available in current tunnel construction,they fail to consider both forecast distance and forecast accuracy;additionally,site testing is complex.The Horizontal Sound Probing Technology(HSP) can solve the above-mentioned problems by means of testing arrangements and data processing technology.This paper presents the principles,testing methods,and knowhow of HSP and analyzes the effects and technical features of HSP on the basis of typical engineering practices.更多还原
