| 摘 要： | 通过对集中荷载作用下颗粒堆中力传递定量实验的概率分析,应用随机理论分析了压力与压痕的相关性,压力值与测试承压板响应的随机波动性;得到了力链从生成到逐渐消失规律的随机模型.结果表明该模型的力扩散过程与实验结果相吻合.

| Abstract: | By means of probabilistic analysis of quantitative experimental data of force transferring in granular medium pack under concentrated load,the correlation between the pressure and its impress and the stochastic fluctuation of the pressure magnitude and response of the tested load bearing plate as well was analysed by using stochastic theory.A stochastic model of force diffusion,which was well consistent with the experiment,was developed. |

| Keywords: | granular medium force diffusion stochastic model Gaussian process |
