[VI-879] Verification of the effect for depression measures of coastal revetment back
Keywords:coastal revetment, roadbed cave-in, vibration of the compulsion harden, electromagnetic wave exploration, water level observation
In late years the roadbed cave-in happens near a truck very very much.
And the cave-in influences the stable transportation of the train.
Therefore, I look for the cavity under the railroad with a hollow space probe for cave-in measures.
Then I harden it by forced vibration and seam filling to prevent a cave-in.
I report a result about these this time.
