摘要
基于铁路工程不良地质勘察规程,将地质分析法、指标评分法及厚跨比法相结合,提出综合集成法,并运用该方法对山西中南部铁路通道的一段岩溶路基进行塌陷性评价。经证明,此方法可以准确判断该段岩溶路基的塌陷性,具有较强的可操作性,并且评价结果符合铁路工程规程相关规定,同时也为路基设计及施工提供依据。
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.
