The invention relates to the measurement of a soil body shear strength property, in particular to an overall-process direct shear apparatus and a measurement method for soil body shear strength. The overall-process direct shear apparatus comprises a shearing box component, a pushing and dragging component and a pressurization component, wherein the shearing box component is used for containing a specimen and comprises an upper box and a lower box; the pushing and dragging component is used for pushing or dragging the shearing box component to separate the shearing box component; the pressurization component is used for providing vertical pressure for the specimen in the shearing box component; and the upper top area of the specimen filling cavity of the lower box in the shearing box component is greater than the lower bottom area of the specimen filling cavity of the upper box in the shearing box component to enable the contact area of the lower bottom of the specimen of the specimen filling cavity of the upp
