| 摘 要： | 通过对碎石桩复合软土路基进行现场沉降监测试验,得到其竖向沉降规律。基于D-P模型,应用FLAC3D岩土工程数值分析软件对加固后的碎石桩复合软土路基竖向沉降进行数值模拟,并对数值模拟沉降值和现场监测沉降值进行对比分析,发现二者较为吻合,此数值模拟方法可应用到碎石桩复合软土路基沉降计算及预测中。 |

| Abstract: | The vertical settlement deformation law is obtained by monitoring in-suit vertical settlement of the gravel pile composite soft soil subgrade. Base on D-P model, the vertical settlement deformation of the reinforced gravel pile composite soft soil subgrade is simulated with the FI.AC^3D software. It is almost identical between the simulated value and the in-suit monitoring value through comparing analysis. Then, the numerical simulation method is applied in the calculation and prediction of the gravel pile composite soft soil subgrade. |
