摘要
管幕法及其改进工法的结构承载力整体较高,适用于地表沉降控制严格、环境敏感的地下工程,与其他工法的结合可进一步拓展管幕法的使用范围.但管幕的钢管连接锁口处是整个结构的薄弱环节,如何减少连接数量及加强连接处的强度成为管幕技术发展的主要研究方向,其成果可为管幕法的理论研究和工程实践提供参考和借鉴.
Abstract
This paper introduced the origin and characteristics of the pipe curtain method.It then analyzed the im-proved forms of the method,summarized its construction points,and described its current situation when combined with other methods.Finally,it provided an overview of the engineering application of the pipe curtain method.The research results indicate that the pipe curtain method and its improved construction methods have a high overall structural bearing capacity.This makes them suitable for underground engineering projects that require strict surface settlement control and sensitive environment.The pipe curtain method can significantly expand its scope when com-bined with other construction methods.However,the locking mechanism of the steel pipe connection in the pipe curtain is the weakest link of the entire structure.Minimizing the number of connections and strengthening their strength has become the main research direction for the development of pipe curtain technology.The research re-sults can provide reference and inspiration for the theoretical research and engineering practice of the pipe curtain method.
