摘要
Abstract
In order to estimate the impact of new subgrade on existing roadbed, this paper integrates the composite foundation lateral friction to derive the formulas for calculating the superimposed stress in soil subject to lateral friction load based on Mindlin’s formula in semi-infinite elastic body and the assumption that the composite foundation is taken as a whole reinforcement body. The lateral superimposed stress of the soil at the filled slope toe under the action of the composite foundation is also calculated.关键词
