Study on Solidification Treatment of Electrolytic Manganese Slag and Numerical Simulation of Slope Stability

Abstract

Manganese slag contains a large number of easily migrated heavy metals and ammonia nitrogen and other pollutants, which have a negative impact on the ecological environment. To verify the feasibility of manganese slag as highway subgrade material, manganese slag samples were solidi ed by mixing y ash, cement and quicklime, and the solidi cation effect was compared. The permeability coe cient, cohesion and internal friction angle of manganese slag were measured by permeability test and triaxial test. On this basis, optimization of manganese slag road sections under different slope heights and different slope ratios in a total of 50 schemes was carried out. GeoStudio software is used to perform nite element simulation on the slope stability of manganese slag slopes under dead weight and rainfall.This study provides a reference for highway construction projects using manganese slag.

Analysis of Basic Physical and Chemical Characteristics of Manganese Slag before and after Solidification and Its Feasibility as Highway Slope

“…Mehdizadeh et al developed a modified triaxial apparatus connected to a water supply system and collection tank to investigate the post-erosion behavior of soil under different loading patterns in undrained conditions [25]. In this study, the data of numerical simulation are from experiments [26]. The manganese slag in this state was solidified in advance.…”
