土钉墙支护破坏原因分析与控制

Analysis and Control Measures to the Destruction of Soil-nailed Walls

根据有关土钉技术及其应用的研究,分析得出:土体性质的改变、土与土钉之间相互作用被破坏、土钉自身强度不足和面层被破坏是引起土钉墙支护结构破坏的主要原因,同时还讨论了土钉墙支护破坏的控制措施.

Based on the study of soil-nailed walls and its application, some factors are regarded as the main causes of destruction of soil-nailed support, which include the character change of soil, the interaction between soil and soil-nail, the low soil-nail intensity and destruction of concrete surface layer. Several kinds of control measuers to prevent destruction of soil-nailed walls are discussed.
