Using φ2.5 mm×5 m pothole,the experimental study of the interaction between blast wave and structure in highly saturated soils is accomplished systematically.According to recorded waveforms of stress,strain and momentum,the experimental results are interpreted.The experimental results indicate that blast loads on structure are not much more than value of pressure in free field;loads on roof of structure are more uniform than expected value;the overall deformation of structure is generated under blast loads,central loads are used to take place the entire loads;whether or not there is the shock wave,the law of reflection is the same;blast wave velocity and the reflection coefficient of structure increase with saturation degree.
