土钉支护结构中,基坑的阴角和阳角部位空间效应较明显,存在明显的三维效应。一般分析往往对基坑进行简化,将基坑中剖面的分析结果应用于基坑角部部位,结果与实际情况存在差异。通过基坑监测和三维有限元分析,证实了土钉支护结构角部部位具有明显的空间效应,基坑阴角处较阳角处具有较高的安全性。

Concave location effect and convex location effect of soil nailing supported structure are obvious.Analysis of the central section of soil nailing supported structure was different from analysis of the concave location and convex location of soil nailing supported structure.In this situation,the construction monitoring data of a project in Beijing and the calculation data of the three-dimensional finite element model was analyzed.The results show that the concave location is more secure than the convex location.
