Time, the paper studies rheology of rockfillwith yin zongze model, of two yield surface and rheological relation of negative exponential, and some formulas are obtained it is difficult to determine the rheological parameters, of rock fills through laboratory test for the limited specimen, dimension, short duration and particle, constituents
本文採用殷宗澤雙屈服面模型與堆石流變的負指數變化關系式，研究堆石的應力與流變關系，並推導了相應公式。在流變參數確定方面，由於室內試驗的試樣尺寸、時間比尺和顆粒破碎很難模擬現場條件，根據室內試驗直接確定堆石的流變參數是困難的。
