【摘要】：地下连续墙作为一种重要的围护、防渗、承重结构,在岩土工程中扮演着不可或缺的角色。本文回顾了地下连续墙的诞生及设计方法与施工技术的发展,并展望了地下连续墙的发展趋势。地下连续墙的计算理论从古典法逐步过渡到弹性抗力法与连续介质有限元法的结合,结构形式从单一的壁板式进化到T形、圆形、格栅形、"∞"形等多种异形结构形式。用途也更加广泛:从初始的防渗墙到挡土结构、承重结构再到"二墙合一"、"三墙合一"。新型施工机具、工法的出现,使得挡土、承重地下连续墙往深、大方向发展,防渗墙往薄壁方向发展。随着实用本构模型的开发,参数选取的更加合理化,异形结构计算理论的发展,地下连续墙设计将更加高效,合理。
[Abstract]:As an important retaining, impervious and load-bearing structure, underground continuous wall plays an indispensable role in geotechnical engineering. This paper reviews the birth of underground continuous wall and the development of design method and construction technology. The development trend of underground continuous wall is prospected. The calculation theory of underground continuous wall is gradually transferred from classical method to the combination of elastic resistance method and finite element method of continuum medium, and the structural form evolves from single wall plate type to T shape, circular form.
