摘要
通过工程实例，论述了设计轮廓面开挖采用预裂爆破或光面爆破应根据岩石性质、开挖部位的轮廓形状、预裂缝成型的难易程度、爆破对周围重要设施的影响等多种因素确定，即两种开挖方法应根据客观条件提到同等地位选用。
Through investigation in engineering practices,whether to apply presplitting or smooth blasting technology in excvation of slope contour designed should depend on some factor,such as rock characteristics,excavation contours,liability to form presplit cracks,effects of blasting on nearby important installations,etc..In other words,these two excavation methods should be put on an equal footing according to practical conditions.
