摘要
高边坡问题在基础建设的发展过程中不断出现,尤其是泥岩边坡问题。文中通过分析泥岩边坡6种病害坡体结构:顺倾层状结构、反倾层状结构、陡倾层状结构、基座式上软下硬结构、交叉式楔形结构,得出了泥岩边坡在不同坡体结构下可能的破坏方式;最终归纳总结出了5种典型的泥岩边坡破坏模式:风化剥落、楔体破坏、倾倒破坏、滑移-拉裂破坏、牵引式滑动破坏。
High slope problems appear constantly in the development of the infrastructure,especially the issue of mudstone slope.Different slope structure possible failure mode of the mudstone slope is obtained in this paper through analyzing 6kinds of mudstone slope disease slope structures:consequent dip direction layered structure,reverse dip direction layered structure,craggy dip direction layered structure,pedestal soft hard structure,crossing wedge structure.Finally 5kinds of typical mudstone slope failure modes:weathering flake,wedge failure,dumping destruction,slipping-cracking destruction,traction sliding are summarized out and the necessary basis for further evaluation of mudstone slope stability is put forward.
