摘要
山西省汾河二库碾压混凝土重力坝枢纽工程,两岸高边坡(105～95m)开挖中采用了预裂及深孔爆破,应用孔外微差分段爆破技术取得良好的施工效果。在大坝基础岩石开挖中采用一次性保护层开挖新技术,经试验测试及竣工验收,达优良工程的标准。
Rork foundation excaration of Fenhe Erku RCC Gravity Dam of Shanxi province has gained good construction effect. Presplit holes and deep hole blasting and millisecond subsection blasting technology are used in this project's high slope excavation with stope weights of 105～90 m. The new technique of excavation with protected cayer over pleted by only one time is adopted in rock excavation of dam foundation. This project achieves excellent project's standard through experiment and completion examination.
