Abstract: This paper mainly solve the problem of internal force calculation of the foundation beam,whichis partly separeted from the foundation and loaded on the border.

Key words: foundation beam, partly separeled from, addttional settement :repeatedly calculation

摘要： 本文通过分别求出基础梁的挠度值和地基沉降值，并对它们进行比较，然后采用迭代求解的方法，不仅较好地解决了基础梁在有局部脱空情况下的内力求解，而且还解决了由边荷载等因素所产生的附加沉降值所引起的基础梁的内力变化。
