介绍了管桩复合地基在某高速公路软基试验工程中的应用,并简单分析了其加固效果,进而结合已有的研究成果,提出了一套路堤下刚性桩复合地基的设计理论。通过工程实践表明,该设计理论具有在工程实践中推广运用的价值。
This paper introduces the application of pipe pile composite foundation in a soft ground experimental project of a expressway, and simply analyzes its reinforcement effect. Then based on the existing research results, a design theory of rigid pile composite foundation under embankment is proposed. Through engineering practice shows that the design theory has the value of promoting the use of engineering practice.
