设有土层锚杆的地下室底板设计实例

通过对土层锚杆进行的抗拔试验,得出其在循环加载作用下的Q-S曲线。采用SAP2000设计软件,将土层锚杆模拟成具有相应刚度的弹簧支座继而进行地下室底板的有限元计算分析,得出其在受变形控制时的受力图,达到完成构件的结构设计工作。

The Design Example of Basement Floor with Soil Anchor

Through the tensile test for the soil anchor, the Q-S curve was obtained under the effect of cyclic loading; Using the design software of SAP2000 to simulate the soil anchor as a spring bracket with the corresponding stiffness, and proceed the basement floor of Finite Element Analysis, obtain the force diagram under the control of deformation to achieve the component structure of the design work.
