Guangxi Charcoal Mudstone Side Slope Preventing And Controlling Engineering Research

Along with our country reform and open policy thorough and the economical highspeed growth, the first-class highway, the railroad, the water conservation and so on themassive engineering project completes or is constructing, can produce each kind of typeside slope in the construction process, these side slope quality becomes the influenceengineering project transport business the primary factor. Because the different sideslope project the tax saves frequently in the different engineering geology environment,how acts according to the different geological environment, reasonably effectively selectsthe side slope stability analysis and the reinforcement method which adapts with it, isquestion which is worth studying thoroughly.This article first through the consult massive materials, the system summarizedthe domestic and foreign charcoal mudstone nature and the charcoal mudstone sideslope preventing and controlling technology related achievement, has provided thepowerful basis for this topic.Then by liu zai to shui ren what the second-class road charcoal mudstone sideslope is a backing, unifies own project practice, carries on the investigation and theresearch to the Guangxi charcoal mudstone side slope, studies: (1) charcoal mudstone inGuangxi's distributed condition; (2) Guangxi charcoal mudstone chemistry and mineralingredient, as well as physics mechanical properties; (3) Guangxi charcoal mudstoneproject characteristic; (4) influence charcoal mudstone side slope stable primary factor;(5) charcoal mudstone main distortion destruction pattern; (6) charcoal mudstone stableappraisal and classification; (7) basis side slope classification, specifically explained each kind of side slope preventing and controlling technology.Finally through the typical charcoal mudstone side slope analysis and theapplication, proves the preamble the research results: (1) uses the FLAC procedure andthe limiting equilibrium computation method separately to six strongholds to the liu zaito shui ren what the second-class road K56+660～+860 road section charcoal mudstoneside slope carries on the stable analysis and the appraisal, has proven its analysis resultuniformity; (2) use preamble research results, through the plan optimization design,found have suited this side slope the preventing and controlling measure: Thepre-stressed anchor cable anti-slippery pile and the vegetation slope protectiontechnology, lays with mortar the comprehensive program of public order plan which theslabstone slope protection unifies; (3) through the construction and the observation,confirmed its punishment plan scientific nature.
