红粘土原状土样保护方法的研究

STUDY ON UNDISTURBED SAMPLE PRESERVATION OF RED CLAY

红粘土具有高含水量、高塑性的特征 ,极易收缩而产生裂隙。红粘土原状土样难予进行长期有效的保护。结合工程实例研究表明 ,红粘土原状土样埋藏、裹浆是其有效、方便、经济的保护措施。

Characterized by high water content and high plasticity,the red clay is easy to contract and yield joints.It is difficult to effectively preserve undisturbed sample of red clay in a long term.Based on the case history,the authors propose an effective,easy-doing and economic preservation method.
