Analysis of Bazimen landslide soil by laser-induced breakdown spectroscopy

An experimental device with laser-induced breakdown spectroscopy(LIBS) for detecting the soil samples was built. The soil samples were researched by the device. According to the same latitude and different height, five locations in Bazimen landslide near Three Gorges Dam were selected to sample. The LIBS spectra of the five samples were obtained. The qualitative and quantitative analyses of Mg, Si, K, Al were performed. The result show that the content of these-elements decreased with the declining height.
