The tests show that it is available that the competent factor F of the rocks is measured by the powder-breaking method or the method applying the test hammer for sedimentary rock which is often confronted in colliery. Value F of rock can be calculated by applying different empiric formulae according to the height of the rock powder obtained, when the powder-breaking method is applying. Vario us values of rebound are obtained when applying the test hammer on the standard sample and block for the same...

Different results of calculating water hammer in series pipes or simple pipes can be quickly obtained by keying in various data. ( without modifying the program ) It may be used for water hammer calculation...

In this general program, the characteristic method of equal time interval grid is used for calculating water hammer, the gate is nonlinearly (or linear ly ) opened and closed. The program is concise, accurate, and easy to use. Less memory elements and shorter calculating time are needed only. Different results of calculating water hammer in series pipes or simple pipes can be quickly obtained by keying in various data. ( without modifying the program ) It may be used for water hammer calculation in combined series pipe-lines and various simple pipe-lines, such as steel pipes, reinforced concrete pipes in open air, non-lined tunnels, underground pipe-lines (steel plate liner, reinforced concrete liner, and combined liner), etc. It is especially efficient to calculate water hammer for many different cases.

本通用程序中,水击计算采用等时段网格特征线法,阀门启闭为曲线(含直线)变化规律。本程序结构紧凑,需要存贮单元少,使用方便灵活,节约计算时间,成果精度高,只要从键盘上改变输入的数据(程序本身不需更动),便能迅速得到相应情况下,串联管或简单管的水击计算结果。可用于露天钢管、露天钢筋混凝土管、无衬砌隧洞和埋藏式管道(钢板衬砌或钢筋混凝土衬砌或混合衬砌)等组合的串联管,以及各种简单管道的水击计算。特别对于大量不同情况下的水击计算更显优越。
