摘要
文中重点阐述在Sap84结构分析软件下,采用增量法和总量法进行工况组合的建模方法。通过对各施工阶段的受力转换分析,重点解决增量法建模时围岩、围护及主体结构的内力、位移及刚度增量的计算,并对增量法和总量法进行对比,为逆作法结构设计提供借鉴。
This article focuses on the method of modeling the combination of operating conditions using the incremental method and the sum quant method under the Sap84 structural analysis software.Through the analysis of the stress conversion at each construction stage,the increment of internal force,displacement,and stiffness of the enclosure,the main structure,and the surrounding rock were calculated.The comparison results of the two methods may provide a reference for the similar reverse design structure design.
