摘　　要：结合开洞生态复合墙体在水平及竖向荷载作用下的受力特点,采用基于抗剪抵抗机构理论,建立开洞墙体在极限状态下的抗剪抵抗机构体系。通过数值扩展分析,推导出开洞墙体斜截面受剪承载力计算公式,并确定开洞墙体斜压杆有效强度系数的合理取值。试验研究、理论分析及数值模拟表明:提出的开洞生态复合墙体斜截面受剪承载力计算公式,具有一定的理论依据和实用价值,满足实际工程计算需要。Combined with mechanical characteristics of open-hole eco-composite wall in horizontal and vertical loads and based on the shear resistance mechanism theory, the holed wall＇ s shear resistance mechanism system in simit state was set up. Through the numerical analysis of extension, inclined section shear bearing capacity calculation formula of the open-hole wall was deduced, and determined the reasonable value of the holed wall oblique compression bar effective strength coefficient. Test research, theoretical analysis and numerical simulation show that the proposed holed eeo-eomposite wall inclined section shear bearing capacity calculation formula has the certain theory basis and practical value, which can meet the need of actual engineering calculation.
