摘　　要：主要阐述了深基坑桩锚支护结构计算常用的两种方法,经典法和弹性法,并以厦门某酒店基坑支护(桩锚支护)为例,利用计算软件,分别模拟出基坑开挖的各个工况及受力特点,通过比较两种方法的计算结果及实际监测数据分析,结果表明弹性法比经典法更符合实际情况,且弹性法中增量法考虑了上一步开挖对下一步开挖的影响,更科学合理。This article mainly expounds two kinds of method commonly used to calculate the pile anchor supporting structure for the deep foundation pit,the classical method and elastic method.Taking a hotel foundation pit supporting in Xiamen(pile anchor supporting)as an example,the computing software was used to simulate the various conditions of the foundation pit excavation and mechanical characteristics.The calculation results of two methods were compared,and the actual monitoring data was analyzed,the results show that elastic method is more conforms to the actual situation than classic method,and the incremental method of elastic method considers the impact of the previous excavation on the next excavation,so is more scientific and reasonable.
