Method and device for measuring and calculating shear strength of cement mixing pile composite foundation
The invention relates to a method and a device for measuring and calculating shear strength of a cement mixing pile composite foundation, which are characterized in that a pile-soil test piece model of the cement mixing pile composite foundation is established on the basis of a double-scale calculation method according to different parameters of a cement mixing pile, and rigidity parameters of a pile-soil test piece model matrix are endowed, so that the shear strength of the cement mixing pile composite foundation is measured. Finite element data information is imported into an operation program in MATLAB, material information is calculated, a Poisson's ratio mu and an elastic modulus E are predicted through a computer program language, a cement mixing pile composite foundation model under corresponding conditions is established in finite element software, strength data parameters of soil blocks and rigidity data parameters of the soil blocks are input respectively, and the model is established; and extracting a required data curve to obtain shear strength parameters.
