By far , two hypotheses on foundation model has been widely adopted : one is winkler foundation model ( k foundation model ) that foundation response modulus k is used to characterize foundation rigid ; the other is elastic half - space foundation model ( e foundation model ) that elastic modulus e0 and poisson ratio 0 are used to characterize foundation rigid . in the present paper , e foundation model is adopted to simulate half - space elastic foundation body 目前廣泛使用地基假設(shè)有兩種,其一是以地基反應(yīng)模量k表征地基剛度的文克勒( winkler )地基假定(簡(jiǎn)稱為k地基) ;其二是以彈性模量e _ 0和泊松比_ 0表征地基剛度的彈性半空間地基假定(簡(jiǎn)稱為e地基) ,本文采用e地基。
