摘要
为研究填石路基土石比和压实方案对工程质量的影响,论文依托实际工程,在试验路段进行路基压实等各道工序,采用不同土石比和压实方案进行施工,并对竣工后填石路基进行沉降量与压实度检测。结果表明,最佳土石比为50∶50,压实方案采用分层碾压且碾压遍数不得低于7遍。
In order to study the influence of soil to rock ratio and compaction scheme on engineering quality of rockfill roadbed,based on the actual project,the paper carries out various processes such as roadbed compaction in the test section.Different ratios of soil to rock and compaction schemes were used for construction,and the settlement and compaction degree of rockfill roadbed were tested after completion.The results show that the optimal ratio of soil to rock is 50∶50,and the compaction scheme adopts layered rolling and the number of rolling times should not be less than 7 times.
