Comparative Analysis Of Twice Soil-alike Slope Excavation

Soil-alike slope is a new type slope in current slope fields and it belongs to thecategory of artificial slope. This article is studying at the foundation of Xingfen road whichis the natural ground before. It occurred slight slope collapse phenomenon after the first cutof Xingfen high speed soil-alike slope.To ensure the safety of the project,we decided toconduct a secondary slope cutting.Through on-site survey-jointed Analysis-numerical simulation-stability analysis ofthis basic research methods, this article selects nine representative slopes and establishubiquitous-joint models by FLAC-2D software which developed by ITASCA company.Thispaper analysis the stability of soil-alike slope excavation under the combined action of twojoints from the theoretical point of view.I hope my study will provide a reference for thefuture operation of the actual engineering.Currently,FLAC-2D is used to analysising most of the simple bedding slopes, there aresome limitations on handling complex slopes with different groups of rock joints. Thispaper build separate models with different joints,and analysis data by weights to simplifythe process of operation.By comparing the changes of displacement and stress field,I havedrawn that the second slope-cut makes the project much more safer.
