永久性格构式土钉挡墙探讨
摘要:目前土钉墙多用于基坑支护,起临时性支护作用,使用年限不长。若在土钉墙中以土钉为交点,设置横梁竖柱可像格构式锚杆挡墙一样构成永久性格构式土钉挡墙。通过实例对永久性的格构式土钉挡墙的设计方法、构造处理及施工要求等方面进行探讨,供土建人员参考。

Abstract:At present, nailing walls, which have short service life, are usually used for foundation pit supporting and the temporary protection. If people make the soil nailing an intersection in the soil nail gun, they can set the beam and upstand like the lattice anchor rod retaining wall as well as the lattice soil nailing retaining wall. This paper introduces the method of calcu lating, the construction management and the requirements of construction of soil nailing used for permanent retaining wall through a practical project. It can be served as reference for the designers of such structures.
