加筋砂土地基承载力理论与试验分析研究

加筋地基由于其加筋机理的复杂性,其设计和计算理论的研究还是远远落后于工程实践。依据普朗德尔关于地基的基本假定和分析方法,分析了砂土加筋地基的加筋原理;推导了单层加筋地基极限承载力的近似解;讨论了加筋地基承载力与加筋长度和埋置深度的关系等问题。通过与有关加筋地基的模型试验的对比分析,验证了理论分析的合理性和正确性。

Theory and experiment on bearing capacity of reinforced sandy soil

Because of the complexity of reinforcing mechanism of reinforced ground,its design and theoretical researches fell far behind the engineering practice.According to the Prandtl’s assumption and analytical method of foundation,the principles of reinforced sand were analyzed,the approximate solution of bearing capacity for the single-layer reinforced sand was derived,and the relationship between length,depth of reinforcement and bearing capacity of reinforced sand was discussed.By contrast to the related model test of reinforced sand,the rationality of theoretical analysis were indicated.
