摘　　要：为了研究刚性衬砌渠道受冻胀时衬砌层的受力状况 ,通过模型模拟试验研究 ,找出了刚性衬砌渠道受冻胀时边坡衬砌层 (板 )的受力情况与其下渠床土含水量沿渠道横断面高度分布之间的内在规律 ,为寒区刚性衬砌渠道如何采取防冻胀措施提供了科学依据。For researching stressing status of rigid lining of canals under frost upheaval, through experimental research with simulation model, the rules of relationship between stressing status of rigid lining under frost upheaval and canal bed soil's moisture cantents which are varied with heights of the canal's cross sections, are found out. The results provide a scientific basis for adopting measures to prevent frost upheaval of the rigid lining canals.
