［摘要］依托SAP2000建立研究对象的精细化有限元结构分析模型，分析水浮力作用下考虑锚杆（桩）对地下室底板的有利作用和不考虑锚杆（桩）对地下室底板的有利作用的结构精确内力，进而将锚杆（桩）对地下室底板的有利作用进行量化。利用SPSS软件对锚杆（桩）刚度和弯矩系数进行线性回归分析，发现板弯矩系数和锚杆（桩）刚度之间具有明显的线性关系。最后得到考虑锚杆均匀分散布置对底板配筋的有利作用时锚杆（桩）刚度和弯矩系数的线性回归方程，可求得不同锚杆刚度下的弯矩系数。

Abstract: Relying on the SAP2000 establish the refined finite element structure model, analyze the internal force of soleplate under the condition of considering the beneficial effect dispersed float resisting anchor played on soleplate and without considering it, which can make the beneficial effect qualified. The relationship between bending moment coefficients of slab and anchor stiffness has significant linear correlation, by carrying on the linear regression analysis using SPSS software. Finally get linear regression equations between bending moment coefficients of slab and anchor stiffness when considering the beneficial effect dispersed float resisting anchor played on soleplate and then the bending moment coefficients under different anchor stiffness are obtained.

Keywords: SAP2000; float resisting anchor; internal force of soleplate
