摘要
对于高耸结构在极限工况下对基础底部脱开面积,目前各个规范均有控制要求,但均未给出确定的计算方法。这对于工程师设计基础而言颇为不便。以方形基础为例,基于半平面接触应力理论和线弹性应力分布假设,分别推导和对比了基底脱开面积和接触应力的不同计算方法。类似地,以圆形风电机组基础为例,分别基于半空间接触应力理论和线弹性应力分布假设,也做了分析和对比。脱开比例限制和计算公式可作为实际工程设计分析的参考。
In limit design states,the different limitations of gapping between the subsoil and the foundation slab of high-rising structures have been requested in existing technical norms,however,the calculation methods of gapping are not given very clearly.This is really inconvenient in foundation design for engineers.Taking the rectangular foundation as an example,based on the half-plane contact stress theory and the linear elastic stress distribution assumption,the different calculation methods of base gapping area and contact stress are deduced and compared respectively.Similarly,taking the circular wind turbine foundation as an example,based on the half-space contact stress theory and the linear elastic stress distribution assumption,the analysis and comparison are also made.The gapping limitations and formulas can be use as a reference for actual engineering design analysis.
