| 摘 要： | 在描述土钉支护软土边壁(坡) 相似模型试验现象和结果基础上, 对其加固、支护机理作了探讨。分析了土钉弓形受力分布有一个产生、形成、发展和畸变的过程, 并非如C. K. Shen 等人给出的固定弓形形态。同时论述了土钉支护面层的鼓形受力特点, 与软土边壁的流鼓破坏模式密切相关。

| Abstract: | The phenomena and results of similar model tests on soil nail support in soft clay side walls(slope) are described, and then the reinforcement and support mechanism are discussed. The bow shaped stress distribution of the soil nail presents a process of initiation, formation, development and distortion, rather than the fixed bow shape given by C.K.Shen and others. Meanwhile, the convex shaped stress features of the surface layer is discussed, which is closely related to the Flow convex Failure Pattern (FFP) of soft clay side walls. |
