某道路沉降段路面有限元研究

将Abaqus有限元技术与道路沉降相结合,并根据张家口地区新建道路的现场监测试验数据以及当地地质环境条件,建立道路沉降有限元模型。数值模拟法试验表明,道路实际沉降值在检测完毕后,沉降为3.196~5.544 mm,而Abaqus有限元模拟得出的道路沉降值为2.229~4.135 mm,二者差距并不大。以此验证了Abaqus有限元模拟道路沉降技术在实际工程中的适用性。

Finite Element Study on Pavement in Road Settlement Section

Abaqus finite element technology is combined with road settlement.And based on the field monitoring test data of new roads in the area of Zhangjiakou and the local geological environment conditions,the finite element model of road settlement is established.The numerical simulation method test shows that the actual settlement value of the road is 3.196 mm^5.54 mm after the detection,while the Abaqus finite element simulation shows that the settlement value of the road is 2.229~4.135 mm.There is no significant difference between the two.Thereby,this proves the applicability of Abaqus finite element simulation road settlement technology in practical engineering.
