摘要： 为解决传统数值模拟方法在对高层建筑地基承载力极限数值模拟时存在模拟精度低的问题，开展高层建筑地基承载力极限数值模拟研究。通过建立高层建筑地基承载力模型、设置约束条件及计算地应力、模拟不同基底条件下承载力数值变化，提出一种全新的数值模拟方法。通过实验证明，新的数值模拟方法在实际应用中能得到与实际更接近的结果，并且模拟精度达小数点后两位，能够有效提高数值模拟结果的精度，可为高层建筑施工设计及各项施工措施提供更准确的数值参考依据。

Abstract: To solve the problem of the large difference between the simulation results and the actual value when the traditional numerical simulation method is used to simulate the limit value of the bearing capacity of the geomaterials for the high-rise buildings, which causes the low numerical simulation accuracy, a numerical study of the limit value of the bearing capacity of the geomaterial for the high-rise building is presented in this paper. A new numerical simulation method is proposed by establishing the bearing capacity model of the geomaterial for the high-rise building, setting constraint conditions and evaluating the ground stress, and simulating the numerical change of bearing capacity under different base conditions. Experiments have demonstrated that the new numerical simulation method can obtain results closer to actual values in practical applications, and the simulation accuracy can be significantly improved, which can provide a more accurate numerical reference basis for the construction of high-rise buildings.
