Method for determining roadbed rolling process of granite residual soil
The invention relates to a method for determining a roadbed rolling process of granite residual soil, which comprises the following steps: S1, obtaining the optimal compaction work Wc based on the relationship between the number of compaction times and the dry density of improved soil; S2, obtaining a conversion relation between a compaction test and a road roller, converting the optimal compaction work Wc into vibration compaction energy W of the road roller, and determining a rolling scheme of the road rollers with different tonnages; and S3, based on the rolling scheme, obtaining the rolling frequency of the road roller under different tonnages by changing the virtual paving thickness value. According to the method, the stability and the compression resistance of the roadbed are remarkably improved, the workload and the working time are greatly reduced, and the construction cost is reduced.
本发明涉及一种用于确定花岗岩残积土的路基碾压工艺的方法，包括：S1、基于击实次数与改良土干密度的关系，得到最佳击实功Wc；S2、获取击实试验与压路机具的转换关系，将所述最佳击实功Wc转化为压路机振动压实能量W，确定不同吨位压路机的碾压方案；S3、基于所述碾压方案，通过变换虚铺厚度值，得出所述不同吨位下压路机的碾压遍数。本发明方法显著提高了路基的稳定性和抗压性能，大大减小了工作量和工作时间，降低了施工成本。
