description The invention discloses a test device and method for simulating interaction of a distributed post-grouting pile-soil system. The device comprises a grouting sample manufacturing box and axial pressure compensation equipment acting on the grouting sample manufacturing box. A grouting pipe is led out of a hole formed in the side wall of the lower box of the grouting sample manufacturing box and is connected with a grouting device for injecting cement grout through a flow dividing valve, a grouting control sensor is arranged on the grouting device, and the grouting device is connected with a data acquisition instrument to monitor and store dynamic changes of key grouting parameters in real time and transmit the dynamic changes to a computer control system. According to the method, the problem of considering the influence of actual grout injection on the shear characteristic of an interface and the uniformity and uniformity of batch sample manufacturing is solved, and an effective test means is provided for resea
