海相黏性土状态与直接快剪试验指标的经验关系

THE EXPERIENCE RELATIONSHIP BETWEEN THE STATE AND THE DIRECT SHEAR TEST INDEX ABOUT MARINE FACIES CLAYED SOIL

摘要: 通过对大连海域第四系全新统海相黏性土385组试验数据的统计与分析,建立了第四系全新统海相黏性土(Q4m)液性指数IL与直接快剪试验指标-黏聚力Cq、内摩擦角q的经验关系,即Cq=10.623 I-1.8114L; q=-3.8289ln(IL)+5.8634。

Abstract: Based on the 385groups test data about marine clayey soil (Q4m) in Dalian sea area,this paper established the experiential relationship between the liquidity index (IL) and direct shear test index(cohesion (Cq)、angle of internal friction (q)) about marine clayey soil(Q4m):Cq=10.623 I-1.8114L、q=-3.8289ln(IL)+5.8634.
