摘　　要：桩基托梁挡土墙结构为复合结构,挡土墙和桩基托梁是一个整体,不能孤立考虑。根据桩基托梁挡土墙支挡结构的受力特点,提出抗滑型和承载型两种桩基托梁挡土墙计算模式,结合工程实例进行了数值模拟计算。数值计算结果与假设的计算模式吻合,说明假设的计算模式是合理的。The pile foundation-trimmer beam retaining wall structure is a compound structure which is a whole,pile foundation-trimmer beam and retaining wall can＇t be respectively considered separately.Based on the stress characteristics of the structure,the two computation models of anti-slide model and bearing model were suggested,and combined with the practical project,numerical simulation analysis was made.The results of numerical computation and hypothetic computation modes are identical,so the hypothetic computation modes are reasonable.
