包砂路基越来越广泛地应用于高速公路工程 ,由于砂土与粘土工程性质差别较大 ,二者结合部成为影响工程质量的关键所在 ,也是施工的难点。本文从实践出发 ,围绕解决砂土、粘土结合部的质量问题 ,提出了包砂路基的施工工艺 ,对指导施工以及施工规范的制定具有一定的参考价值
As the sand embankment is more and more widely used in highway engineering, due to the difference of the engineering properties of sand and clay, the combination of the two has become the key to the quality of the project, which is also the difficulty of construction. Based on the practice, this paper put forward the construction technology of the sand-filled roadbed around solving the quality problems of the sand and clay joints, which has certain reference value for the guidance construction and the construction specification
