【摘要】 本文结合多处高速公路软基沉降实测资料 ,从分析软土路基沉降及差异沉降规律入手 ,讨论了路基沉降对基底附加压力的两点影响 ,对Balight大面积堆载的一维理论作了更便于工程应用的修正 ,并将其推广到适用于路基等有不均匀沉降时的情况更多还原

【Abstract】 According to practical settlement data of several superhighway soft soil subtrade,the rules of embankent settlement and differential setllement of subgrade were analysed and the effect of subgrade settlement on the additional stresses in two aspects are discussed.The Balight’s one dimensional theory under large area loading was adjusted to fit for engineering practice.The conclusion has been extended to the case of differential settlement.更多还原
