抗浮锚杆布置形式的数值模拟与对比分析

Numerical Simulation and Comparison Analysis of Different Arrangements of Anti-floating Anchor

抗浮锚杆由于布置灵活,造价合理,常被用作地下室抗浮措施。常用的抗浮锚杆布置方式有均匀布置和梅花状布置两种,但何种锚杆布置方式更经济、有效缺乏相应研究。通过运用ANSYS有限元软件,采用薄板的小挠度理论,对实际工程中锚杆均匀布置和梅花状布置两种形式进行有限元分析,发现采用梅花状布置时底板受力更小,锚杆受力更均匀。

Anti-floating anchor is often used as anti-floating measures of basements. The common use of arrangement forms includes uniform arrangement and plum shape arrangement form, but which one is more economical and effective still lacks appropriate research. This paper analyzes the effects of two arrangement forms and draws a conclusion that foundation slab bears smaller stress and anti-floating anchors are stressed more uniformly when plum shape arrangement form is adopted, according to the theory of thin plate with small deformations by ANSYS finite element software.
