摘　　要：K104+500～K104+640段紧靠既有线(黔桂线),行车密度大;岩石坡面组成主要为石灰岩,石质坚硬,局部岩石有破碎。施工方案要求该段切方较深(16m),爆破对岩体强度的层面粘聚力的损失较敏感。路堑施工时,必须采用安全合理的爆破技术。K104＋5-K104＋640 section nears the exsiting line（Qian-Gui Line）, its driving has big density, and its rock slope composed of limestone whose stone is hard, and some local rocks have broken. Construction scheme requires the cut square more deeper （16m）. The blasting is sensitive to cohesive strength loss of rock strength. In the cutting construction, we must adopt safe and rational blasting technology.
