摘　　要：作为一种常见的地基处理方式,灌注咬合桩在深基坑领域中应用广泛。为了评估和预测灌注咬合桩的竖向承载力,结合中国铁建华南总部大厦基坑工程咬合桩情况,提基于ABAQUS数值模拟方法进行灌注桩竖向承载力模拟分析。通过混凝土桩与钢筋混凝土桩的交叉连接,对灌注桩的竖向承载力进行分析。研究结果表明:在地应力和周围土压力的作用下,咬合桩主要应力分布在钢筋混凝土桩中部和交叉连接处。通过工程桩基承载力与预测值进行对比,检验了咬合灌注桩模拟结果的可靠性。As a common foundation treatment,perfusion occlusal pile is widely used in the field of deep foundation pit.In order to evaluate and predict the vertical bearing capacity of the perfusion pile,combined with the situation of the occlusion pile in the foundation pit project of China Railway Construction South China Headquarters Building,the ABAQUS numerical simulation method was proposed to simulate and analyze the vertical bearing capacity of the perfusion pile.Through the cross connection of concrete pile and reinforced concrete pile,the vertical bearing capacity of cast-in-place pile is analyzed.The results show that,under the action of in-situ stress and the surrounding soil pressure,the main stress of the occlusal pile is distributed in the middle of the reinforced concrete pile and the cross connection.By comparing the bearing capacity of the engineering pile with the predicted value,the reliability of the simulation results of the occlusal cast-in-place pile is tested.
