摘要
传统的土钉墙都是由高耗能高排放的水泥和钢筋构成。毛竹是一种可再生资源,具有抗拉强度高,短期强度相对稳定,长期强度逐渐降低。毛竹的这种特性,符合建筑基坑支护临时性特点。本文提出的低碳环保型毛竹复合土钉墙基坑支护技术,具有取材科学合理、绿色环保、经济、安全等优点,有着广阔的应用前景,是对现行土钉墙的结构用材和构筑理念上的重大突破。具体措施是,在基坑土钉墙支护结构中以毛竹取代了钢质土钉,面层砼中用竹篾网取代钢筋网,基坑坡脚的毛竹排桩与毛竹土钉连在一起构成复合土钉墙结构,能使基坑得到可靠的支护。文章详细阐述了毛竹复合土钉墙基坑支护机理、数值分析、计算方法及工程应用。
Bamboo is a kind of renewable resources with characteristics of strong reproductive capacity , quick grown and short growth cy-cle.In this paper, a new foundation pit support technology of bamboo composite soil nailing wall which is low carbon environmental protec -tion was introduced.This technology has advantages of scientific and reasonable , green environmental protection , economy, safety, etc. And it has a broad application prospect which is a breakthrough of current soil nailing wall structure material and building concept .Its tech-nique detail is applying bamboo instead of steel soil nail in the foundation pit soil nail wall supporting structure and bamboo split net instead of steel fabric in surface concrete , so the bamboo piles at foundation pit slope foot and bamboo soil nailing together constitute the structure of composite soil nailing wall , can get reliable support of foundation pit .The article expounds on the supporting mechanism , numerical a-nalysis, calculation methods and engineering application of bamboo composite soil nailing wall foundation pit .
