摘要
采用快速拉格朗日分析方法(FLAC 3D)对粉喷桩与土工格栅联合加固地基进行数值模拟,探讨联合加固后地基的位移场、应力场的变化规律,并与实际监测分析结果相对比,得出一些有意义的结论。
The reinforcement technology of dry jet mixing pile combined with geogrid is simulated by three-dimensional fast Lagrangian method (FLAC-3D).The displacement field and the stress field are discussed of the roadbed that has been reinforced. Compared with the monitor data of the scene, some valuable conclusions have been obtained.
