在分析重庆山区土石混填地基强夯加固机理的基础上,结合工程实际探讨了各种强夯加固深度确定方法的有效性、合理性。分析结果表明:对于山区土石混填地基,孔隙比测量、室内击实试验等方法单一现场试验检测评价方法可靠性低、成本高,只有综合采用瑞雷波、荷载板和动力触探法才是经济、适用、可靠的检测评价法。
Based on the analysis of the dynamic compaction and reinforcement mechanism of soil-rock mixed soil in Chongqing mountainous area, the effectiveness and rationality of various methods for determining the depth of dynamic compaction reinforcement are discussed based on engineering practice. The results show that the reliability and cost of a single on-site test method for rock-soil mixed-soil foundations, void ratio measurement and indoor compaction test in mountainous areas are low, and the cost is high. Only the combination of Rayleigh wave, load plate and dynamic probe method Economic, applicable and reliable testing and evaluation method.
