摘要
土钉支护是用于深基坑开挖支护的一种新方法,近年来复杂地质条件下的土钉支护工艺研究取得了很大的进展,得出了一整套的先进施工技术,使土钉支护技术在杂填土、松散砂土、软塑或流塑土、软土中也得以应用,并可与砼灌注桩、钢板桩及止水帷幕等配合使用进行支护,从而扩大了土钉支护的使用范围。经大量工程实践验证,取得了良好的效果。
The earth nail support is a new method used in the support of excava tion of the deep foundation ditch. In recent years, the research on earth nail t echnique used in complicated geological conditions has obtained very big progres s, and a package of advanced construction techniques has been put forward, which makes the earth nail supporting technique be applied in miscellaneous fill, inc ompact sandy soil, soft plastic or fluid plastic soil, and soft soil, and can be used together with concrete caisson pile, steel sheet pile and waterstop draper y, etc., expanding the serviceable range of the earth nail supporting technique. A large number of engineering practices verifies that this technique has obtain ed good results.
