爆破堆石坝堆石体主要工程地质研究

Main engineering geologic research of blasted rockfill dam body

定向爆破筑坝是爆破岩体工程地质力学、爆炸力学、爆破工程学相互交叉、渗透并有机结合而形成的一种筑坝技术,他具有节省筑坝石方施工工程的造价,加快施工进度的优点。然而,爆破筑坝技术在水利建设筑坝中的应用,还须进一步研究解决爆破堆积物本身工程地质问题及水文地质问题以及周边影响带的同类问题。以己衣水库为例对爆破堆石坝堆石体的工程地质问题进行了研究。

Building dam by directional blasting is a dam construction technology formed by mutual intersection, permeation and organical combination of engineering geologic mechanics, blasting mechanics and blasting engineering, and has advantages of saving cost and speeding up construction progress. In order to better apply the technology to the water conservancy project construction, problems on engineering geology and hydrologic geology of the blasting accumulation body itself and its surrounding affected zones should be further investigated and solved. Taking Jiyi reservoir for example, the problems on engineering geology of the rockfill body of the rockfill dam formed by blasting are studied.
