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。
Based on a large number of practical and productive tests, a set of methods for filling the embankment by directional blasting is proposed in this paper. By using the principle of slump sliding and the method of triangle area balance, the stacking rules and calculation of rock after blasting are deduced Formula, after 20 years of more than 400 engineering tests, has become a new type of effective engineering blasting method. There are no retaining walls, slope protection and dry bridges in favorable locations along the Xihe River. Therefore, it has important practical significance and economic value.
