刘浩吾(成都工学院) (一)关于爆破程序当采用两岸布置时,爆破程序确是设计中应考虑的问题之一,原文所得三点结论具有一定的指导意见。但是,研究问题的方法和前提不尽得当。首先是作为平面问题考虑,近似性很大。诚然,多列布置时爆破后堆积轮廓近似一梯形,但相对而言,顶宽不大,且必力求缩小,因而梯形两翼的三角形面积远大于顶宽下面的矩形面积。以充分使用多排多列布置的某定向爆破筑垻工程为例,其顶宽约达70米,但亦仅为底宽的六分之一。可见原文所用“垻轴线剖面两岸单宽上垻方量与堆积
Liu Haowu (Chengdu Institute of Technology) (a) on the blasting program When using the layout of the two sides, blasting program is indeed one of the issues to be considered in the design, the original three conclusions have some guidance. However, the methods and preconditions for the study of the problem are not adequate. The first is to consider as a plane problem, a large approximation. Admittedly, the buoyancy profile is approximately a trapezoid after blasting in a multi-column arrangement, but the top width is relatively small and must be reduced. Therefore, the triangular area of the trapezoidal wings is much larger than the rectangular area below the top width. Taking a directional blasting building project that uses multiple rows and columns as its full foundation, for example, the top width is about 70 meters, but only one sixth of the bottom width. It can be seen from the original text "垻 axis cross-section of the single-width cross-strait square amount and accumulation
