合肥—杭州高速公路 (芜湖—宣城段 )地基是软土层 ,采用粉喷桩及水泥搅拌桩加固地基 ,为了准确快速地检测桩基的质量 ,采用了多种方法进行检测。文中介绍了这些检测方法效果及对比其优缺点 ,探寻一种准确快速的软弱路基施工质量检测方法组合 The foundation of Hefei-Hangzhou Expressway (Wuhu-Xuancheng section) is a soft soil layer. The foundation is reinforced by dry jet mixing piles and cement mixing piles. In order to detect the quality of pile foundation accurately and quickly, a variety of methods are adopted for the test. This paper introduces the effect of these detection methods and compares their advantages and disadvantages, to explore a combination of accurate and fast method of construction quality testing of weak subgrade
