摘要
对大石河尾矿坝的四种配制砂样进行了静力不排水剪切试验，初步探讨了孔隙比、固结应力和固结应力比对土样应力－应变特性的影响，提出了四种尾矿砂配制样的稳态线和稳态强度，并对稳态线的合理性和稳态强度的工程应用进行了讨论。
Behavior of Dashihe tailings sands was studied in consolidated undrained conditions effects of void ratio. effective confinning pressure and consolidation stress ratio on the shape of stress-strain curve was in vestigated. Steady state lines(SSL) and strength of sands were proposed. The validity on SSL and application of steady-state strength to geotechnical engineering were discussed.
