Abstract：
Advance geological forecast technology for tunnels has been growing quickly in recent years and now plays a key role in tunnel construction. 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.
