| 中文摘要:复合土钉支护在软土地区深基坑支护中已得到广泛应用，但其设计计算理论却远远不能满足目前工程应用的需要。借助非线性平面应变有限元模拟方法，对复合土钉支护结构在分步开挖、分步支护过程中的变形性能进行研究，并通过与工程实例对比验证这一方法的合理性。最后对复合土钉支护设计提出初步看法。 |

| Abstract:The composite soil-nailing has been wildly used in the soft soil zone, but its theory for design and calculation cannot satisfy the present project application. With the aid of the non-linear plane strain finite-element, the distortion performance of composite soil-nailing during the step-by-step excavation and supporting process was studied. Through the contrast testing with engineering examples, the rationality of this method was verified. The preliminary view to the composite soil-nailing design was proposed. |
