摘要:
文章以厦门地铁1号线残积砂质黏性土为研究对象,通过标贯试验和室内土工试验,对残积砂质黏性土标贯试验指标N值与部分物理力学参数之间的相关性进行了研究,并给出了线性拟合关系式及其相关系数。研究结果表明:(1)厦门地铁1号线残积砂质黏性土内聚力c、内摩擦角φ、压缩模量Es(1-2 kPa)、地基承载力fk、无侧限抗压强度qu与标贯N值成正比关系;(2)厦门地铁1号线残积砂质黏性土液性指数IL、压缩系数α(1-2 kPa)与标贯N值成反比关系。
Abstract:
Abstract:Taking the residual sandy cohesive soil of Xiamen Metro Line 1 as the research object, the correlation between Standard Penetration Test(SPT)index value N and some physical and partial physico-mechanical parameters of residual sandy cohesive soil is studied by Standard Penetration Test(SPT)and Indoor Soil Test and the linear fitting relations and the relevant coefficient are also deduced from the study. The result of the study shows that for the Xiamen Metro Line 1 the value of N for SPT is in direct proportion to the cohesion c, angle of internal friction φ, modulus of compressibility Es(1-2 kPa), ground bearing capacity fk, and the unconfined compressive strength qu of the residual soil, while it is inversely proportional to the liquidity index IL and coefficient of compressibility α(1-2 kPa).
