摘要
利用有限元软件ABAQUS对桩端后注浆抗压桩进行数值模拟研究,将计算结果与试验实测结果对比,结果表明采用的模型能有效地模拟单桩荷载与沉降的关系;选取注浆量、浆液模量、长径比作为参数变量,利用ABAQUS分析模型中各参数变化对桩端后注浆抗压桩极限承载力的影响,表明注浆量、浆液模量对单桩承载力的影响都有一个限值、桩端后注浆技术对长径比小的桩更有效。
The finite element software ABAQUS is used to numerically simulate the post-grouting pile.The result is compared with the experimental result,showing that the model can effectively simulate the relationship between load and settlement of single pile;Use ABAQUS to calculate the influence of the change of grouting quantity,grouting modulus and length-diameter ratio.The result shows that the influence of grouting quantity and grouting modulus on the bearing capacity of single pile has a limit value and post-grouting technology is more effective for piles with a smaller length-diameter ratio.
