摘要
高液限土在高速公路施工过程中十分常见,但对高液限土进行改良用于路基的填筑还没有统一、规范的施工工艺和质量控制手段。该文通过原材料试验、混合料配比优化、施工工艺参数的优化和成套质量控制技术的完善,形成了一种通过掺砂改良高液限粘土的路基填筑工艺,并在广悟、云罗高速进行了工程应用。
High liquid limit soil is frequently met in the super high way construction, there are no unitive and norm- ative construction and quality control method currently. In this paper, the raw material testing, mixture optimum de- sign and the construction process improvement were studied to produce a serial technology on high liquid soil improve- ment by sand addition. This technology was implicated in Guang-Wu and Yun-Luo super high way.
