落石运动路径按区间分段算法
The Algorithm to Calculate the Rockfall Motion Path with the Partitioning Interval Computation Method
摘要
Abstract
A new algorithm method about the possible motion path of rockfall is proposed,which should be clear in the design of rockfall prevention engineering.According to the rockfall motion state,when the rockfall goes through the different calculation interval,the calculation intervals are divided into seven classes.In the calculation intervals,the motion process is divided by three types including flight,rolling and crash,and the conversion conditions of the rockfall among the three motion types are defined.First,the calculation intervals are classified by the slope surface characteristic;then the motion path of rockfall is calculated in each calculation interval orderly,and the type of the calculation interval should be determined at the same time;so the motion path is obtained at last.For simulating the motion randomness of the rockfall,the key parameters in the calculation are assumed to obey uniform distribution.The correctness of the algorithm is ver ified by a numerical example and the seven kinds of calculation intervals and the results of 20 random calculations are also shown in the example.关键词
