【摘要】 某游泳馆由于地下水位上涨导致结构抗浮承载力不足,造成局部大范围内柱子出现弯曲、弯剪裂缝,后采取泄压、压重等措施,裂缝明显闭合,甚至消失。本文采用ANSYS结构分析程序,用平面刚架模型模拟实际工程情况,计算得到底板位移值与实际工程情况基本一致,并由此计算出地下水压力大小对工程结构后续加固处理有指导意义。更多还原

【Abstract】 In a bathing building,it led the buoyancy resistibility of structure to descend that groundwater level was rising. This resulted in columns appearing many bending and bending-cutting cracks. By taken methods of loading gravity and unloading pressure,these cracks were evidently closed and disappeared. This paper take model of plane frame to simulate the realistic structure by ANSYS program. The calculation from program was close to realistic displacements and helped to strengthening structure in the following work.更多还原
