CFG桩复合地基承载力计算新公式模拟研究

Simulation Study with Improved Calculation Method of CFG Pile Composite Foundation Bearing Capacity

通过Flac3D有限差分软件进行CFG桩复合地基承载力计算方法应用于某工程的模拟试验,研究了处理后的桩间土承载力特征值fsk更趋于合理取值的问题,以便使处理后复合地基承载力更趋于其真实值,而不会在设计时做过于保守的估值;另外通过对处理后桩间土的合理取值能相应地降低工程的造价。

Through that the simulation test that the calculation method of bearing capacity of CFG pile composite foundation is applied to a project,the way that reasonably choosing the value of bearing capacity characteristic value of the soil between piles after treatment is researched to enable the value of the bearing capacity of composite foundation be closer to its actual value and more reasonable,but not ultra-conservatively to appraise its value in the design;in addition,the cost of the project can also be reduced accordingly by this method.
