| 摘 要： | 针对季节性冰冻地区路基土回弹模量的变化,通过室内试槽土基回弹模量试验,对相同状态下的土体分别进行了室内试槽土基刚性承载板和无侧限圆柱形试件回弹模量试验,建立了无侧限圆柱形试件与试槽土基承载板试验回弹模量之间的关系.为下一步进行大量的季节性冰冻地区冻融循环作用下,无侧限圆柱形试件抗压回弹模量换算为试槽土基承载板试验回弹模量提供依据.

| Abstract: | In relation to the change of resilience modulus of subgrade soil in seasonal freezing regions,this paper,based on laboratory resilience modulus test on trail trench soil foundation,carried out trail trench soil foundation rigid bearing plate test and unconfined cylindrical specimen test on the soil mass under the same conditions respectively,and then developed the relationship between the resilience modulus in the both tests,which offered the basis to a large amount of conversion further from compressive modulus of resilience for unconfined cylindrical specimen to that in trial trench soil foundation bearing plate test under the action of freezing and thawing cycle in seasonal freezing regions. |

| Keywords: | seasonal freezing regions trial trench test soil foundation modulus of resilience rigid bearing plate unconfined cylindrical specimen |
