Magnetic Effect on the Engineering Properties of Remolded Cohesive Soil


In recent years, with the rapid development of the global economy and urbanization, the urban electromagnetic environment has become more and more complex; the additional magnetic field cannot be ignored. To study the magnetic effect of remolded cohesive soil, we determined cohesive soil in Shenyang area to the magnetic effect of grain composition and structural strength. The test used two DC power supplies and coils to simulate the magnetic field conditions and analyzed the magnetic effect of the grain composition, the compression property, the shear strength and the subgrade bearing capacity with different magnetic field intensities and the magnetizing times. The results showed that after the treatment of different magnetic field strengths and different magnetization times, small particles in remolded cohesive soil are aggregated, and the percentage of small grains decreased and that of large grains increased. Modulus of compression was gradually increased which showed that the compressibility of soil was decreased. The shear strength and the subgrade bearing capacity were also increased with the increase in the water content. Meanwhile, there existed an optimal water content which made the subgrade bearing capacity reached the maximum. The results showed that after magnetization, the connection between the soil particles was increased and the strength of remolded cohesive soil increased.
