摘要
地下室抗浮设计中,多数采用锚杆方式。文章简述锚杆的受力原理,分析其分别布置在柱底或板中受力状态,并对布置在底板的不同工况进行具体分析。通过对锚杆布置在板中或柱底的安全性分析,结合试验数据和锚杆受力特性,建议锚杆布置在柱底,以减少抗浮设计中的不安全因素。
In the basement anti-floating design,the method of anchor rod is mainly adopted.This paper has briefly described the mechanical principle of anchor rod,analyzed its stress state arranged respectively at the bottom of column or in the plate,and conducted concrete analysis of the different working conditions of anchor rod arranged in the baseplate.Based on the safety analysis of the anchor rod arranged respectively in the plate or at the bottom of the column,and combined with the test data and the stress characteristics of the anchor rod,it is suggested to arrange the anchor rod at the bottom of the column to reduce the unsafe factors in the anti-floating design.
