摘要(Abstract)：

面板堆石坝坝体软岩料开采技术的关键是,在爆破过程中要有效地控制爆落石料的超径大块和细化现象的发生。本文结合大坳、茄子山和鱼跳三个依托工程软岩料爆破开采的经验和教训,在研究软岩的动力特性的基础上,根据地质构造与岩石的成因,将软岩细分为纯软岩、软硬岩互层、软岩中有硬岩岩脉侵入三种工程类型,并有针对性地提出相应的钻爆方法与施工措施。
The problem of excavating soft rock by blasting is how to control in effectively the oversize large blocks and small rock blocks in construction of face rock-fill dam.Based on the experiences and lessons obtained in excavating soft rock by blasting in Da'ao,Qiezishan and Yutiao projects the deferent the drilling methods and construction approaches have brought forward to dealing with the pure soft rock,the soft-hard alternating beds rock and the hard rock vein invaded in soft rock according to their geologic structures and rock formation and the dynamic behavior of soft rock.
