摘要
Abstract
The uplift bearing capacity of anti-floating anchor is affected by factors such as the properties of soil and rock,groundwater,the type of anchor structure,and construction techniques.If there is confined water in bedrock fracture within the depth range of anti-floating anchor,the influence of groundwater on anchor construction should be fully considered,and the appropriate design and construction scheme should be selected according to the engineering geological conditions and engineering characteristics of the site.This paper introduces the design and construction process of anti-floating anchor in a project in Huainan,analyzes why the uplift bearing capacity of anti-floating anchor does not meet the design requirements,and finally selects the underreamed anchor by high-pressure jet grouting,which reduces the length of the anchor,minimizes the entry of the anchor into the aquifer during its construction,plays a certain role in blocking the bedrock fissure water,ensures the smooth construction of the anti-floating anchor and improves its uplift bearing capacity.关键词
