地基的变形计算是地基基础设计的一项重要工作内容,地基的变形可以通过各种方法进行计算,本文以附加应力的明德林解为基础,以花岗岩残积土地基为切入点,提出了考虑基础埋深影响的地基沉降计算方法,更加适合高层建筑沉降变形计算;制定出了与之相应的无量纲系数表;通过具体的工程实例,与以布西涅斯克解为基础的地基沉降计算方法进行比较,此方法所得结果与实测沉降值更加吻合,既保证了安全性,又经济合理,验证了此方法的合理性和科学性。
Deformation calculation of foundation is an important work content of foundation design. Deformation of foundation can be calculated by various methods. Based on the Mindlin’s solution with additional stress, taking the residual soil foundation of granite as an entry point, The foundation settlement calculation method influenced by the depth of foundation is more suitable for the calculation of settlement deformation of high-rise buildings. The corresponding dimensionless coefficient table is developed. Through concrete engineering examples, the method of settlement calculation based on Bussinesk solution The results obtained by this method are more consistent with the measured sedimentation values, which not only ensures the safety but also is economic and reasonable, which verifies the rationality and scientificity of this method.
