The variation laws of dynamic elastic modulus and damping ratio for composite sample of cemented clay?clay are studied experimentally by means of triaxial apparatus. Emphasis is laid on the influence of replacement ratio and confining pressure.

• 通过动三轴试验研究了水泥土复合试样的动模量和阻尼比的变化规律,着重研究了置换率和围压的影响,提出了一种简单实用的计算复合试样动模量和阻尼比的方法,并给出了由试验确定的归一化公式。
