曼维莱高液限粘土作芯墙筑坝材料研究

Study of High Liquid Limit as Clay Core Dam in MEMVE'ELE Hydropower Project

高液限粘土受含水率的影响较大,一般作为填筑料,施工不宜压密,容易造成"弹簧土"现象,进而造成粘土芯墙坝或均质土坝的湿陷开裂,甚至进一步破坏的可能。结合喀麦隆南部曼维莱水电站工程,探讨利用残积高液限粘土作为粘土芯墙坝筑坝材料的可用性。

High liquid limit clay largely affected by water content, as a filling material can＇ t be easily compacted, usually lead to spring soil phenomenon, which causes the clay core dam or homogeneous earth dam collapsibility and cracking, even further damage. In this paper, according to the MEMVE＇ ELE Hydropower Project located in the Southern Cameroon, the authors explore the usability of residual clay with high liquid limit as clay core dam.
