| 摘 要： | 公路工程对湿陷性黄土的研究基本上是采用房建建筑的规范和试验规程进行勘察和设计,由于公路路基的工作环境和受力状态与房建工程地基差异很大,将房建建筑的规范直接应用于黄土地区高等级公路的湿陷性评价与计算存在着盲目性、不合理性,更为重要的是缺乏针对性。本文通过对现有规范在路基黄土湿陷性方面的合理性与实用性研究,结合降雨入渗的分布规律,提出了适合黄土地区高速公路的路基黄土湿陷性评价方法与模型。

| Abstract: | Collapsible loess research of the expressway engineering is basically to adopt the criterion and experiment rules of buildings to investigate and design,due to the working circumstance and mechanics condition different to buildings foundation widely.Applying criterion and experiment rules of buildings directly to collapsibility evaluation and calculation of loess expressway is blindness and inconsequence.The more important is the lack of pertinence.Through the practicability and rationality research on the present criterion to subgrade loess collapsibility,combined the rainfall infiltration depth distributing law,the paper brings forward loess collapsibility evaluation method and model which suitable for expressway subgrade in loess area. |
