摘要
改进大型直剪仪在传统直剪仪的基础上将局部底部剪切盒面积增大,用于沉井当中的侧摩阻力试验研究,解决了传统直剪仪局限性和剪切过程中实际剪切面积不断减小、上下盒边缘处的应力集中明显等问题,能较好地用于沉井侧摩阻力的研究。
Traditional large -scale direct shear appara- tus,referred to large shear apparatus can be used for large- scale coarse-grained soil shear test specimen, the completion of soil samples, geotextile, geomembrane friction large scale direct shear test. Improve the large -scale direct shear instrument in the traditional direct shear apparatus based on the local area of larger box at the bottom of the shear for the sinking of the lateral friction among the pilot study not only solved the limi- tations of traditional direct shear instrument but also can make more good solution to cut the process of con- tinuously decreasing the actual shear area, upper and lower edges of the box clearly focused on issues such as stress, can be well used in well-sinking study lateral friction.
