Research of Acoustic Detection In Reinforcing Highway Slope With Frame Beam And Grouting Bolt

摘要

Grouting bolts are planted partly at the grid of frame beam in reinforcing highway slope. The dimension of frame beam and the length of bolts are the key parameters in design. Based engineering example by acoustic detection, the effect is appraised with the increasing rate of wave velocity along depth direction in detection hole, then the rationality is evaluated for the dimension and of frame beam, and the rationality of anchor length is appraised with the variation trend of wave velocity. In the following, the two reasonable parameters are gained, and the use for reference to similar projects is offered in the future expectably.
