| 摘 要： | 研究目的:目前我国铁路和公路等部门的相关规范对于路基的承载力都没有给出具体规定,导致在铁路工程设计中承载力的取值偏于保守,研究柔性路堤地基承载力控制值具有重要的工程和理论意义。研究结论:通过对遂渝铁路软土路基工点实测承载力的统计分析与研究,指出:对一般路堤、场坪等柔性基础地基,应从路堤稳定性、工后沉降和路基承载力3个方面进行地基加固工程设计;在满足稳定与工后沉降要求的前提下,地基容许承载力的要求可适当放宽,并初步给出了柔性路堤地基承载力验算公式及地基承载力修正系数的建议意见。

| Abstract: | Research purposes: At present,there is no concrete specification stipulated in the relative codes issued by railway and highway authorities in China and this results in the sampling value of the bearing capacity in design of railway project is somewhat conservative.Therefore,the study on the control value of bearing capacity of flexible embankment foundation has the great engineering and theoretical significance.Research conclusions:From the statistical analysis and study on the measured bearing capacity of... |
