Abstract: Based on a large number of practice and production check up, this paper presents a set of procedures for filling up embankment by directional blasting at a close distance. Collapse-slippery principle and triangular area balancing method are used to develop the calculating formulas and law of piling after blasting in various topography. Through four hundred and more applications in the last twenty years, it has become a new effective engineering blasting method, which could be used along a river line without retaining walls slope protection and viaduct. Therefore, it is very practical and of economical significance.

摘要： 根据大量实践和生产性的校核试验,本文提出了一套近距离定向爆破填筑路堤的方法,用坍滑原理和三角形面积平衡方法,推导出在各种地形爆破后岩石的堆积规律和计算公式,经20年400余次工程考验,已成为一类新型有效的工程爆破方法。在沿溪线的有利地段,可不设置挡墙、护坡和旱桥,因此,具有重要的实用意义和经济价值。
