| 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. |
