Strength test and penetration effect of intrusion surface of heavy metal contaminated soft rock

The progressive expansion and contraction damage caused by heavy metal intrusion into rocks is one of causes to the collapse of rock slopes. Based on the shear strength test, point load test, disintegration resistance test, durability test, and weathering test, the mechanical properties of typical h...

description	The progressive expansion and contraction damage caused by heavy metal intrusion into rocks is one of causes to the collapse of rock slopes. Based on the shear strength test, point load test, disintegration resistance test, durability test, and weathering test, the mechanical properties of typical heavy metal contaminated mudstone and sandstone are studied. The spectral band characteristics and spatial frequency changes of mineral elements before and after the intrusion are identified by the spectral diffraction method and acoustic wave detection technology. The penetration effect of heavy metals after an intrusion is analyzed. According to the Weibul1 distribution law of microstructure, the discrete characteristics of intrusion failure of the microelement structure of rock under the single-porous medium, and the relationship between the intrusion performance, elongation performance and time of heavy metals are discussed. The results show that the mechanical strength decreases with the intrusion of heavy metals into rock, and the value reduces with the increasing content of intrusive elements. The differentiation degree of intrusion relationship is shown as the relationship of logarithmic function and power function. The spectral color band characteristics and spatial frequency changes reflect the expansion process of the fissure surface after the intrusion of heavy metal into rock effectively. The penetration effect of microstructure caused by the expansion results in the damage of the integrity of rock. The loss of microscopic mineral colloid particles, the expansion of macroscopic cracks, and the penetration failure are mainly affected by the intrusion and extension properties of the contaminated elements.
