Fast Weathering Law of Red-Bed Mudstone Slope

  • Received Date: 27 Jun 2005
  • Publish Date: 25 Feb 2006
  • To provide a theoretical reference for the protection of red-bed mudstone slopes,a typical red-bed mudstone slope was monitored in the field.In addition,the laboratory experiment and finite element analysis of changes in temperature of mudstone specimens were conducted.The research result shows that the fast weathering of the red-bed mudstone slope occurs within 10 cm depth below the surface,and the variation of air temperature and the number of moderate rainfall have important effects on its fast weathering.The weathering rate increases with the heightening of air temperature and its difference,and the weathering deposits increase with the increment of the number of moderate rainfall.Furthermore,a big air temperature difference between the surface and inside of red-bed mudstone caused by rainfall is the key external factor affecting the fast weathering.
