Application and analysis of new type filter structure in slope protection engineering

More Information
  • Received Date: November 29, 2015
  • Published Date: March 24, 2016
  • A new “M” type filter structure is put forward to solve the infiltration problem of bad geology in Xihepu slope of Huguang-Luohuzhou reach in the middle of Changjiang River. The structure is made of polypropylene mesh core and nonwoven fabric through thermal bonding. The fabric is made by two layers of knitting and heat treatment. The indoor experimental results show that the permeability, soil conservation and anti-clogging property of the new structure can meet the structural stability requirements of revetment engineering. Comprehensive comparison and field test results show that the new structure is applicable to the slope protection engineering in bad geological areas, and it has a better promotion value in the future.
