土钉支护结构的修正折线破坏模式研究

Study on Two-Broken Line Modified Failure Mode of Soil-Nailing Wall Structure

基于土钉支护结构的对数螺旋破坏模式及折线破坏模式,建立了修正折线破坏模式。修正折线破坏模式继承了传统折线破坏模式及对数螺旋破坏模式的优点,较符合工程实际,且破坏模式的确定方法较为简洁。通过工程实例,验证了修正折线破坏模式是有效可行的。

On the basis of log - spiral failure mode and two - broken line failure mode, a two- broken line modified failure mode was set up. The two - broken line modified failure mode inherits the advantages of both log - spiral failure mode and two -broken line failure mode, better accords with the practice of engineering, and its definition is very succinct. Succinct has proved the two - broken line modified failure mode is effective and feasible.
