Study On The Engineering Properties Of Loess And The Stability Of Loess Slope Along A Railway

Engineering properties of loess in the construction of loess areas have a significant impact. With the loess region rapid economic growth, construction efforts have been expanded, increasing human activities in recent years the engineering properties of loess has important theoretical and practical value.With the loess and loess slope of a railway along, for example, on-site investigation, survey and experimental data, combined with multi-disciplinary theories and methods, Study on the engineering properties of loess and slope stability studies, the main conclusions are as follows:1,On the engineering properties of loess in the study area (including collapsible, structural, and mechanical properties of the three major aspects) to experimental data, were analyzed with a proposed " index of engineering properties of loess " concept.2,With " index of engineering properties of loess " based on mapgis platform engineering properties according to different spatial overlay analysis, the engineering properties of regional studies is divided into good, moderate and poor three levels, get their distribution and partition the evaluation.3,The study area of loess slope divided into the new loess slope, the old loess slope, the new and old loess slope and loess + (gravel) +bedrock four kinds of slope classes system; summary of the sensitivity of slope stability factors: rainfall uniformity coefficient, slope, slope structure and slope height. Meanwhile, based on rough set theory, fuzzy comprehensive evaluation method in the study area slope stability evaluation. The results show that the engineering properties of loess slope stability Division and distribution of loess has a good correlation between, for the actual construction has some reference value.
