| 摘 要： | 软土具有很多特殊的性质:天然含水量高、孔隙比大、压缩性强、抗剪强度和承载力低,在软土上修建高速公路引起的沉降也相应具有特殊的规律。本文利用有限元计算方法对软土地基的沉降计算问题进行了探讨,并结合实例进行计算,重点模拟了路堤不同堆载速率、不同宽度、不同填土刚度对软土路基沉降的影响,从而进一步明确了软土路基沉降的特点,为软土路基的设计、施工、监测提供了一定的依据。 |

| Abstract: | Soft soil has many special properties which are different from other kinds of soil, such as: high natural moisture content, great void ratio, large compressibility, low shear strength and bearing capacity. Accordingly, the settlement of highway soft soil subgrade has special laws. This paper analysed the settlement laws of soft soil subgrade using FEM software ABAQUS, and made some relative calculation combined project examples, simulated the settlement of soft soil subgrade with different velocity of load embankment, different width of embankment, and different Young's modulus of fill soil to confirm settlement laws of soft soil subgrade. At last this paper makd some conclusions and gave some advices to soft soil subgrade reinforce, construction and detection. |
| Keywords: | Soft soil subgrade Settlement ABAQUS Finite element method |
