摘　　要：针对沉降计算的可靠性与方便性,提出了一种考虑三向变形的实用沉降计算方法。通过分析Skempton-Bjerrum沉降计算方法的不足,引入土体发生固结沉降时的三向变形效应,采用弹性力学理论,得出了考虑三向变形的沉降计算实用式。并用工程实例分析验证了该方法的可靠性。In order to improve the reliability and convenience of settlement calculation, a practical method for calculating the settlement considering triaxial deformation is proposed in this article. Then, by analyzing the deficiency of the method of Skempt-Bjerrum, the triaxial deformation effect of soil consolidation settlement is introduced. Moreover, a practical expression of settlement calculation with the consideration of triaxial deformation is obtained by the theory of elasticity mechanics. Furthermore, the reliability of this method is studied and proved with engineering cases.
