| Experimental study on dynamic performance in soil compaction of vibro-roller |
| 摘要 |
| 為分析振動(dòng)壓路機(jī)的壓實(shí)動(dòng)力特性，通過(guò)現(xiàn)場(chǎng)試驗(yàn)，測(cè)試了18 t振動(dòng)壓路機(jī)在碾壓過(guò)程中路基產(chǎn)生的動(dòng)應(yīng)力，分析了距離壓路機(jī)不同深度處在不同碾壓次數(shù)條件下的動(dòng)應(yīng)力規(guī)律，結(jié)果表明，一次碾壓過(guò)程中達(dá)到75%最大動(dòng)應(yīng)力的作用次數(shù)為10~12次，碾壓8次后，豎向應(yīng)力基本趨于穩(wěn)定，不隨 |
