CT技术在东风水电站978廊道帷幕灌浆工作中的应用

Application of CT technique to grouting operation of curtain in 978 corridor of Dongfeng hydroelectric power station.

在帷幕灌浆施工过程中,如果首先采用CT技术在先导孔内进行扫描成像,可以了解到帷幕上岩溶构造、透水地层的分布及规模等情况,然后根据不同的地质条件,使用相应的施工方法,可以有效地提高帷幕灌浆质量与效果,并取得良好的经济效益。

During grouting operation of curtain, if first adopting CT technique to scanning imaging in guiding hole, the distribution and scale of karst structure and permeable bed in curtain can be well-known, then according to different geologic condition to use different operation method, which can greatly improve the quality and effects of grout of curtain and achieve good economic benefit.
