摘要:
为揭示半填半挖黄土路基的变形规律及其影响因素，为高填方黄土路基稳定性的评估提供科学依据。以国道G310典型半填半挖黄土路基为例，运用Settle3D软件对不同工况条件下的黄土路基进行精确建模与系统分析。结果表明：自然条件下路基左右侧沉降量差别不大，而降雨条件下原状黄土侧的沉降大于压实黄土侧的沉降，土层交界处沉降差异显著；降雨条件下中心点的沉降曲线在原填土交界处发生转折，表明压实效果显著；各施工阶段间沉降量差值呈非线性减小趋势，但降雨条件下的稳定时间更长。因此施工中控制路基压实度和采取合理的路基防水排水措施非常重要。
Abstract:
In order to reveal the deformation laws of half-filled and half-excavated loess subgrade and its influencing factors,so as to provide scientific basis for the evaluation on the stability of highfilled loess subgrade,taking the typical halffilled and halfexcavated loess subgrade of National highway G310 as an example,the Settle3D software was used to accurately model and systematacially analyze the loess subgrade under different working conditions.The results showed that the settlement on the left and right sides of subgrade under natural conditions had little difference.The settlement on the undisturbed loess side under rainfall condition was greater than that on the compacted loess side,and the settlement on the boundary of soil layer had significant difference.Under the condition of rainfall,the settlement curve of the center point turned at the junction of the original filling soil,which indicated that the compaction effect was remarkable.The settlement difference between each construction stage presented a nonlinear decreasing trend,but the stability time was longer under the rainfall condition.Therefore,it is very important to control the compaction degree of subgrade and take reasonable waterproofing and drainage measures of subgrade.
