摘要
根据紫坪铺工程引水发电洞进水口高陡边坡在施工开挖期岩石开挖爆破引发的爆破振动对预应力锚索的影响,分析了多点位移计测得的位移与时间过程的曲线,得到了边坡下部岩石开挖爆破振动效应与边坡上部预应力锚索拉固作用之间的关系,为进一步优化进水口高陡边坡预应力锚索的设计提供了理论依据。
The curves of displacement-time are obtained from multi-point extensometers to analyze the blasting vibration effect of rock excavation of high slope in Zipingqu Project. Based on this,the relation between prestressed cable and rock excavation blast of high slope is gained. The study results are presented for the prestressed cable design in Zipingpu Project,and can be used to guide the construction there as a theoretical basis.
