According to the high embankment structure of the Ba-quasi Heavy-haul Railway

the paper provides a high embankment slope stability analysis numerical model considering Heavy-duty train vibration load with 3-D nonlinear FEM.We study the different stability for unreinforced and reinforced high embankment slope with geotechnical grilling by the strength reduction factor method.Then the effect of the gritting length and spacing

the height of slope and the top load on the subgrade on the slope stability was investigated.In the numerical model

the M-C elasticplastic constitutive law was applied to the subgrade and the linear elasticity constitutive law was applied to the geotechnical grilling.By calculating the ZK standard live load and equivalent soil column height

the research was converted to get subgrade top load.The paper shows that when the heavy-haul railway high embankment is strengthen by geotechnical grilling

it can effectively improve the stability of high embankment slope

because the lateral slip is limited.The longer the geotechnical grilling and the higher the subgrade

the greater the stability of the slope will achieve

however

the longer the geotechnical grilling space and the more the load on the subgrade

the less stability the slope will achieve.
