在定向爆破筑坝的設計工作中,堆积位置、堆积厚度的計算,目前有体积平衡法和弹道理論法.前一方法是根据有限范围的实际资料总結的公式,应用于普遍的范围尚有一定誤差.后一方法因拋掷能量系数难于正确选定并忽略空气阻力,也有一定誤差. 为了改进后一方法,本文将提出拋擲速度系数、堆积位置和堆积厚度的計算公式,并提出用爆破試驗确定抛擲能量系数的方法.关于抛擲速度系数的計算方法,李君純、談松曦两同志都曾作过研究,本文再补充球形和凹形底面的爆破漏斗抛擲速度系数的計算公式.其他各种不規則底面的爆破漏斗,
In the design of directional blasting dam construction, the accumulation position, the thickness of the accumulation calculation, there are volumetric balance method and ballistic theory method.The former method is based on a limited range of actual data summary formula, applied to the general range of A certain error.The latter method because of throwing energy coefficient is difficult to correctly select and ignore the air resistance, there are some errors.In order to improve the latter method, this paper will put forward the throwing velocity coefficient, stacking position and accumulation thickness of the formula, and proposed blasting The method of throwing the energy coefficient is tested.There are two comrades studied by Li Junchun and Tan Songxi about the method of calculating the throwing speed coefficient, and the formulas for calculating the throwing speed coefficient of the blasting funnel in spherical and concave bottom are added in this paper. Various other irregular bottom blasting funnel,
