在大型土石方工程中常用的密孔爆破法、预裂爆破法和光面爆破法，虽然能取得较好的边坡稳定和平整度理想的效果，但成本较高，工期较长，且常受到地形条件的限制。根据岩石爆破径向裂隙构成原理，提出了单孔或多孔切槽定向爆破方法，它是一种成本低廉、施工速度快、且边坡稳定性良好的削坡爆破方法。不过这种削坡爆破理论，仍需在实践中进一步探索和研究。 The dense hole blasting method, pre-split blasting method, and smooth blasting method commonly used in large-scale earth and stone works can achieve good results in the stability and flatness of the slope, but the cost is high, the construction period is long, and often the terrain is affected. Conditional restrictions. According to the principle of radial fracture formation in rock blasting, a single-hole or multi-hole directional blasting method is proposed. It is a kind of slope cutting blasting method with low cost, fast construction speed and good slope stability. However, this kind of slope cutting blasting theory still needs further exploration and research in practice.
