Abstract Array horizontal sound probing is a new geological prediction method that can detect adverse geologic bodies (belts) based on energy excited by hammers or electric sparks during tunnel construction. Its technical advantages are summarized by a description of its application in prediction of karst caves, joint-dense fracture zones and fault zones. An introduction to the basic principles, data processing software, instrumentation and test layouts for the array horizontal sound probing method is presented.
