摘要

针对堆石料现场碾压试验，研究基于颗粒流的仿真模拟新方法。首先，以随机多边形颗粒簇形式，建立堆石料的颗粒流模型，充分体现了堆石料的级配、细观组构和破碎效应，从而可以较为真实地模拟堆石料在碾压过程中的宏、细观力学响应；然后，提出振动碾压荷载及碾压过程的模拟新方法，实现振动碾压荷载及碾压过程的仿真模拟；最后，结合水布垭主堆石料的现场碾压试验，利用该方法进行模拟验证，从而论证该方法的可靠性。该方法可为仿真模拟堆石料碾压试验以及研究碾压效应对堆石料宏观力学特性的影响奠定基础，具有重要工程指导意义。

Abstract

This article develops a new method using particle flow code (PFC) to simulate the roller compaction test of rockfill. Firstly

a PFC model composed of random polygonal clusters is established. By considering the grading

meso-structure and breakage phenomenon of rockfill particularly

the model can simulate the macro and meso mechanical responses of rockfill during rolling compaction progress. Then

a new technology is developed to simulate rolling compaction load and rolling compaction progress

and adopted for simulating the in-situ compaction test. At last

the roller compaction test of rockfill in Shuibuya project is simulated. The results of numerical model and physical sample are compared qualitatively and analyzed in detail

which validates this numerical method. This new numerical method will play an important role in simulating the rolling compaction of rockfill quantitatively and studying the roller compaction effect on rockfill.
