摘要
主要研究了路基回填土压实过程中,碾压方式、回填土含水量、碾压遍数等因素在碾压施工中对压实度的影响程度。试验结果表明:影响路基回填土的压实度主次因素是回填土的含水量>碾压方式>碾压遍数;其中影响路基回填土压实度显著性因素为回填土的含水率,最优值为回填土最大含水量,非显著性因素为碾压方式和碾压遍数,其中碾压方式最好为振动碾压和静压结合。
This article mainly researched the influence degree of crushing method,backfill soil water content,grinding times on compactness. Results show that the primary and secondary order influencing subgrade backfill compactness is backfill soil moisture,crushing method,grinding times. The main factor is backfill soil moisture content. Optimal value is the maximum moisture content of the backfill. Non-significant factors are crushing method and grinding times. The best crushing method is the combination of vibrating rolling and static pressure.
