摘要
Abstract
Based on Specification for Unfavorable Geological Condition Investigation of Railway Engineering,a new meta-synthesis method was proposed in this paper combining with the geological analysis method,multi-index integrated assessment method and the cave thickness-span ratio method.By using this new meta-synthesis method,the collapsibility evaluation of a length of karst subgrade on the Mid-South Region Railway in Shanxi was carried out.It has been proved that this new method can accurately judge the collapsibility of this length of karst subgrade,with stronger maneuverability; and its evaluation results not only can accord with the relevant provisions of railway engineering standards but also can provide basis for subgrade design and construction.关键词
