【摘要】 本文对于水工建筑物的均质和非均质土壤地基提供了一个考虑土壤侧向变形影响的沉降量计算方法。文中也讨论了一些代表土壤压缩性质的指标的测定方法,并且指出在计算非均质的土壤地基中的应力分布时,可以按照这些指标在地基中变化的情况去选择适当的应力计算公式。文中并附有适合于各种不同荷重和地基条件的矩形与条形基础应力表多种供设计者采用。此外对于刚性基础的平均沉降量和转动量也建议了简捷的估算方法。更多还原

【Abstract】 This paper presents a new method of settlement analysis taking into consideration the influence of lateral deformation of foundation soils.The method is adaptable to homogeneous and nonhomogeneous soil foundations of hydraulic structures.In the paper,various experimental procedures for the determination of some indices defining the properties of soil compression are discussed.It has also been pointed out that in computing the stress distribution in nonhomo- qeneous soil foundations,we can,according to the variation of these soil indices within founda- tion,choose the appropriate formolas,corresponding to different“stress concentration factors”, for the evaluation of stresses.Stress tables for the vertical normal stress and the sum of the 3 principal stresses for rectangular and striping footings under various loading conditions and corresponding to different stress concentration factors are provided.In addition,a simplifying method for estimating the average settlement and angular rotation of rigid footing is discussed.更多还原
