Abstract: Based on the distributio n and spreading laws of the theoretical subsidary stress produced in varioussoil by foad,and combiming with the foundation settlement phenomenon in project.The umified calcula-tional model of various foundation is put forth by using load-transmission angle. On account of whichthe uifluence of load to the internal force of foundation beam may be calculated.

Key words: foundation beam, load-transmission angle, spreading of stress in triangle, effective limitedcompresible layer

摘要： 本文根据荷载在各种地基土中所产生的理论上的附加应力的分布和扩散规律，并结合实际工程中所出现的地基沉降现象，提出了用荷载传播角把各种地基用同一近似计算模型统一起来，以此计算各种地基上的基础梁板。
