摘　　要：论证了胶结土在剪切带上的胶结强度Sc就是该土的凝聚力C，并通过微观实验数据和方法求算了剪切带上的Sc为20．8kPa，此值与实测的c值19kPa非常一致。研究结果表明，岩土介质的力学特性与其微观特性存在相互依存性。||关键词##4胶结;;氢键;;胶结强度;;Cementation strength Sc on the shear plane in soil is demonstrated as cohesion c in it. Through evaluation by microscopic experiment data and microscopic method, Sc is 20. 8 kPa. Determined by experiments from soil mechanics, c is 19. 0 kPa. Here Sc is nearly equal to c. Reserch results show that mechanical properties of rock and soil depend on their microscopic properties.
