基于ANSYS的扩底桩基础抗上拔性能工程校核

摘要

Ultimate uplift is an important basis in the design of high-tension transmission line.The theoretical value and the practical check of the ultimate uplift have an important effect on the quality of electric power line engineering operation.Though the deviation between theory and practice makes it difficult to work out actual value,a certain deviation is allowed in the actual construction.Taking the excavation pile foundation engineering as an example,we use ANSYS to analyze and calculate the ultimate uplift of enlarged toe pile.The calculation results are consistent with theoretical results,which prove that using finite element to verify the enlarged toe pile is feasible.%抗上拔性是高压输电线路基础设计的一项重要依据,理论值与实际抗上拔力的校核对电力线路工程作业质量有着重要的影响,理论与实际的偏差并不能使我们得出基础的实际抗上拔力,但实际施工中允许存在一定误差;以掏挖式灌注桩基础工程为例,利用ANSYS软件对扩底基础抗上拔性能进行分析计算,计算结果与理论结果相符,证明利用有限元验证基础抗上拔的方法具有可行性.
