Article Preview

The instability of permafrost directly results of the differential settlement of railway subgrade, which brought a great threat to the security operation of railway. In order to obtain the top-limit (zero-temperature interface) data of permafrost, according to the testing environment and the requirements for and use of different dielectric constant, using ground-penetrating radar (GPR) detection. The experimental results show that the method is accurate and effective, and we can get better material data on the zero-temperature interface.
