钙质砂莫尔-库仑强度特性三轴试验测试

Mohr-Coulomb Strength Parameter Tests in Triaxial Shearing Testing Device

随着近海工程建设的不断发展,作为建筑基础材料的钙质砂越来越重要,其强度特性对工程设计和建造具有主要影响,研究其力学性质具有工程意义。对取自我国某海域钙质砂进行了同一干密度、不同围压下的常规三轴试验,并分析整理数据,得到了其应力应变规律及强度参数,对珊瑚地基建筑结构物的地基设计具有借鉴意义。

With the development of the near shore engineering projects, the calcareous sand has been widely used as an impor- tant construction material. The strength properties of the calcareous sand is critical to the engineering design and construction. This paper presents the triaxial test results on the calcareous sand samples prepared at the same dry density but under different confining pressures. The shear strength parameters are obtained for the design and construction of marine facilities in the coral sand soils.
