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。
Relying on SAP2000 to establish a refined finite element structural analysis model of the research object, this paper analyzes the favorable internal forces of the structure taking into account the favorable effect of anchors (piles) on the basement floor and the beneficial effects of the anchors (piles) on the basement floor, Which in turn quantifies the beneficial effect of the anchor (pile) on the basement floor. Linear regression analysis of the stiffness and moment coefficient of bolt (pile) using SPSS software found that there is a clear linear relationship between the plate bending moment coefficient and the rigidity of the bolt (pile). Finally, the linear regression equation of the stiffness and moment coefficient of anchor (piles) in consideration of the beneficial effect of the bolts distributed evenly on the bottom plate can be obtained, and the bending moment coefficient under different anchor stiffness can be obtained.
