The results shows that porosity of rock is the main factor affecting the velocityoflongitudinalwave. The shale content has a smaller affect on the wave velocity than sh…
The relationship between uniaxial compressive strength and the velocityoflongitudinalwave of concrete material with different grading is found through laboratory testing.
通过试验得出不同级配混凝土试样的纵波波速与其单轴抗压强度的关系。
