摘要
通过对已有文克尔地基模型的研究得知,此模型不能完整的将土介质的连续性、分层特性、地基中的剪应力以及应力扩散等特性包含进去,提出了一种改进的文克尔地基模型,指出该模型考虑了土体受力的连续性,使基础和地基之间受力和变形更接近于实际状态,地基刚度的折算值也变得更加精确、合理。
Through studying the soil model of WinNer, it can be seen that this model not include the soil continuity and layered property, shearing stress in soil and stress diffusing. An improved soil model of Winkder is proposed in the paper, such model considers about the soil continuity, makes the force and distortion more close to the practice, and the converting value of ground rigidity more accurate and rational.
