Summary:The invention relates to a pore-exploration and pore-forming device and method for soil stratum ground stress testing and application of the pore-exploration and pore-forming device and method. The pore-forming device comprises a negative pressure soil pumping mechanism, a soil pumping pipe and a soil cutting mechanism, wherein the soil cutting mechanism communicates with the negative pressure soil pumping mechanism through the soil pumping pipe, and soil cut by the soil cutting mechanism is pumped and then discharged by means of negative pressure difference of the negative pressure soil pumping mechanism. According to the pore-exploration and pore-forming device and method for soil stratum ground stress testing and the application of the pore-exploration and pore-forming device and method, steel shells are adopted for wall retaining, a specially made cutter is adopted for cutting soil, pores can be formed quickly through a geological pore-exploration and pore-forming technology of pumping soil through negati
