高速公路路堤下复合地基研究的探讨

Discussion on the Composite Foundation under the Embankment of Highway

现行的刚性基础下复合地基理论并不适用于高速公路路堤工程,对路堤下复合地基的研究已成为当今工程界的热点.根据国内外文献资料,对路堤下复合地基的研究现状进行了分析,总结了国内外三大类研究方法即试验研究、理论计算和数值模拟的研究成果,分析了研究中存在的问题,对今后的研究工作提出了若干建议.

The theory of composite foundation used today does not fit embankment of highway. Its research is becoming a hot topic. According to geotechnical literatures, the current research situation are explained. A summary is made on study results by three methods used at home and aboard：the experiment method, the theoretical analysis method and numerical simulation method. The existing defects are explained and some recommendations about research work in the future are made.
