从土石混合料的压实机理出发,深入分析不同含石量的土石混填路基压实度检测试验中对检测结果产生影响的各种因素,并通过数值分析方法对室内击实试验数据进行拟合,求解理论最大干密度和最佳含水量,采用不同含石量的等效最大干密度法对采用灌水法检测得到的土石混填路基现场干密度值进行修正,消除数据的离散性。分析结果表明,通过修正得到的土石混填路基的压实度均满足工程要求。
Based on the compaction mechanism of soil-stone mixture, various factors that affect the test results in the test of compaction degree of soil-stone mixed subgrade are analyzed in depth. The data of indoor compaction test are simulated by numerical analysis The theoretical maximum dry density and the optimal water content were solved. The equivalent dry density of different stone content was used to correct the field dry density value of soil-rock mixed embankment detected by irrigation method, and the data dispersion was eliminated. The analysis results show that the compaction degree of the soil-rock mixed embankment obtained by the amendment meets the engineering requirements.
