摘　　要：文章通过对比分析两种支护结构的选型考虑要点,以及现场多工况下的锚索应力、位移变形,与软件计算和实际数据进行对比分析,发现管桩+锚索方案存在锚索施工质量不高时位移变形过大的风险性,灌注桩+锚索方案受锚索的影响小,安全储备度高,并对两种桩锚支护结构在项目设计选型和施工过程中的质量管控措施提出建议。By comparing and analyzing the selection considerations of the two support structures,as well as the stress and displacement deformation of anchor cable under multiple working conditions on site,and comparing them with data calculated by software and actual data,it is found that the scheme of tubular pile+anchor cable has the risk of excessive displacement deformation when the construction quality of anchor cable is not high,the scheme of cast-in-place pile+anchor cable is less affected by anchor cable and has high safety reserve.Suggestions are put forward for the quality control measures of the two kinds of pile-anchor support structures in the project design selection and construction process.
