    Abstract
  • A clear understanding of the geotechnical mechanical properties and engineering characteristics of foundation rock mass is very important to evaluate the safety and stability of engineering projects. Based on a large infrastructure project during the 13th Five-Year Plan period in Yuxi, Yunnan Province, the physical and mechanical properties of moderately weathered and strongly weathered carbonaceous slate in the main foundation soil layers in this area were deeply discussed. Firstly, uniaxial compression tests of moderately weathered slate under natural and saturated conditions were carried out based on indoor physical tests. The influence of water content on the uniaxial compressive strength of slate was revealed, and the typical failure mode of slate under uniaxial stress was discussed. Secondly, the gradation characteristics of strongly weathered slate were described based on the indoor particle analysis test. What is more, the variation of shear strength index of strongly weathered slate under different water content was discussed based on the in-situ shear test. Finally, the chemical composition of moderately weathered slate and the permeability and bearing capacity of strongly weathered slate were studied in detail based on three kinds of geotechnical tests. The results can provide guidance for the construction with similar geological conditions in this area.
