摘要
济邵高速公路采用强夯法处理泥岩和泥质砂岩填料的路基。文章针对强夯加固效果、施工质量进行研究,寻找对其进行快速检测评价的方法。通过大量的现场强夯试验,分别采用瑞利波、动力触探和固体体积率检测等手段进行检测,对比检测结果,瑞利波法作为该类软岩填筑路基的检测评价具有方便、快捷、准确和经济的特点。
Jiyuan-Saoyuan Expressway deals with mud rock and sandstone filled subgrade with dynamic consolidation. This paper studies the heavy tamping effect and construction quality to seek for a method for rapid detection and evaluation. Through a large amount of site consolidation test, it carries out detection separately with the measures of Rayleigh wave, dynamic penetration and solid volume fraction. Through contrast of the results, Rayleigh wave method is convenient, swift, precise and economic for detection and evaluation of soft rock filled subgrade.
