摘要
根据膨胀土产生膨胀性土压力的规律 ,并结合加筋土的加筋和破坏机理 ,由极限平衡分析理论 ,提出了考虑膨胀力作用的加筋膨胀土地基的极限承载力公式 ,为确定加筋膨胀土地基的承载力提供了理论依据 ,并可供设计时参考。
It make the theoretic basement for determining the bearing capacity of reinforced-expansive soil foundation and make the reference for the engineering design in this thesis, through establishing the formula of limit bearing capacity considering the expansive earth pressure about reinforced expansive soil foundation based on balance theory of no return, which is based on the distribution of expansive earth pressure produced in expansive soils and on the reinforced mechanism and failure one of reinforced-earth.
