摘要
依托某高速公路高液限土路基,利用数值模拟技术对其进行动力稳定性分析。结果表明:交通荷载作用下,高液限土路基顶部位置稳定性最差,且路基路面中部位置沉降量最大,相应的成为容易产生道路病害的位置;高液限土路基靠近边坡的位置为稳定性较差的位置,易造成边坡滑塌等现象;改良后的高液限土路基沉降量和横向位移明显得到控制。
Based on the high liquid limit soil subgrade of a highway,the dynamic stability of the subgrade is analyzed by numerical simulation technology. The results showed that: under the action of traffic load,the top part of high liquid limit soil subgrade has the worst stability,and the settlement in the middle part of the pavement is the largest,which makes it easy to cause road diseases,the position of high liquid limit soil subgrade near the slope is the position of poor stability,which is easy to cause slope collapse and other phenomena,the settlement and lateral displacement of the improved high liquid limit soil subgrade are obviously controlled.
