| 摘 要： | 以往对真空预压的数值模拟简化太多,以至于计算结果与实测结果差别较大.该文考虑真空度损失和渗透系数的非线性变化的影响,应用ABAQUS较好地模拟了真空预压的整个施工过程,与现场实测的分层沉降较为吻合,施加荷载、控制孔隙水压力的方法正确且具有实际意义.

Numerical Simulation for Vacuum Preloading based on ABAQUS |
| |
| Abstract: | In the past,too much simplification of the numerical simulation for vacuum preloading caused big difference between the results by calculation and measurement.In this paper,considering the impact of vacuum loss and non-linear change of permeability coefficient,the whole construction process of vacuum preloading is simulated by ABAQUS well.It is agreement with the layered settlement by field measurements.The methods of applying load and controlling pore water pressure are correct and have practical significance. |
