摘 要: 土钉墙技术近40年的发展史可分为三个阶段:在第一阶段诞生及基本成形,第二阶段开始理论指导实践,目前已进入第三阶段——使用与改进阶段。土钉墙在国内应用一直以基坑工程为主,在国外用于永久性工程较多,技术特点有所不同。土钉墙在国内应用中存在着变形较难控制、对周边环境扰动较大、可能会占用红线外地下空间、偷工减料现象严重等缺点,限制了其应用,在基坑技术中的使用率前几年达到高峰后,近几年已呈理性下降趋势,并将进一步降低到合理程度,但仍有广阔的应用前景。土钉墙的变形、无损检测方法、复合与组合支护、永久性及防腐技术、在各种特殊性及不良土质中的研究应用将成为今后土钉墙技术研究应用的方向与重点。 There are three stages in the development of soil nail walls in recent 40 years.This technology was born and almost formed at the 1st stage,the theories began to guide practice at the 2nd stage,and now its at the 3rd stage,i.e.,application and improvement stage.The technical features are as follows: it is mainly applied to the foundation pit engineering in China and mainly to the permanent engineering in other countries.It is under reasonable restrictions these years because of some disadvantages and will be gradually reduced,but it still has wide development prospect.The deformation,non-destructive testing method,combined support technology,permanency proofing technology,use in all kinds of bad ground,etc.are the study direction and key to the technology of soil nail walls in the future.
