Effect of earth reinforcement, soil properties and wall properties on bridge MSE walls

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 5,   Pages 1209-1221 doi: 10.1007/s11709-021-0764-2

Abstract: The effects of pore pressure, soil cohesion, earth reinforcement type and length, breakage/slippage ofResults showed that the wall movement is affected by soil pore pressure and reinforcement integrity andSoil cohesion has a minor effect, while the movement increased by 13–20 mm for flexible geogrid reinforcedIf steel grid is used, non-cohesive soil is recommended to minimize corrosion.Proper soil drainage is important for control of pore pressure.

Huang Yishen,Xu Xuefeng,Yao Chunyan,Hu Jiande and Peng Wei

Strategic Study of CAE 2012, Volume 14, Issue 10,   Pages 82-89

Abstract:

The absorption characteristics of cationic polyelectrolyte PDADMAC and anionic polyelectrolyte PSS on benzoguanamine formaldehyde (BGF) particles are investigated. The charging characteristics of BGF particles are changed and controlled using electrostatic self assembly method. A variety of PEi BGF/SiO2 composite abrasives are obtained. The as prepared samples are analyzed by Zeta potential analysis, transmission electron microscope (TEM) and thermogravimetric (TG) analysis. The composite abrasives slurries are prepared for copper polishing. The polishing results indicate that it is SiO2 abrasives, not only coated SiO2 abrasive on polymer particles but also free SiO2 abrasive in slurry, that offer the polishing action. The material removal rates of copper polishing are 264 nm/min, 348 nm/min and 476 nm/min using single SiO2 abrasive slurry, PE0 BGF/SiO2 mixed abrasives slurry and PE3 BGF/SiO2 composite abrasives slurry respectively. The surface roughness Ra of copper wafer (with 5 μm×5 μm district) is decreased from 0.166 μm to 3.7 nm, 2.6 nm and 1.5 nm, and the surface peak valley values Rpv are less than 20 nm, 14 nm and 10 nm using these kinds of slurries respectively.
