新安江水电站2号、3号坝段厚层页岩化灌加固试验研究

Experiment study on clay shale reinforcement at BL2 and BL3 in Xin'anjiang dam

本文介绍了新安江大坝2号、3号坝段厚层页岩泥软化问题,通过室内选材试验和现场化学灌浆试验及检测分析,可以认为本次厚层页岩化灌加固处理试验结果较为理想,能够满足设计最低技术要求。

In this article the problem of thick strata shale in BL2 and BL 3 turning softening in Xin'anjiang dam is introduced. On the basis of lab experiment for materials selection, chemical grouting experiment performed in the field and detection, it is believed that the experiment results be preferable and be able to meet the technical requirement at least.
