The application discloses a kind of based on
tunnel boring machine feedback sensing's penetration method,
system and storage medium, the method comprises: model construction, the
discrete element simulation model that can be used to describe the interaction process of penetration probe and
karst surrounding rock is constructed;
Simulation and calculation, based on
discrete element method, gradually loading
simulation is carried out, penetration probe continuously acts on the surrounding rock model containing filling
cave structure, the data of
penetration process are recorded and the related energy subentry is calculated, and the
risk index is calculated in combination with fracture index;Optimization control,
feedback control is carried out according to
risk index.The
system comprises: construction unit, penetration
simulation unit, calculation unit and control optimization unit.A kind of storage medium,
computer program is stored, program is executed when processor realizes the steps of penetration method as described above.The application can simulate the fracture evolution and energy release process when shield cutter penetrates filling
cave area.The application can be widely applied in the technical field of
tunnel engineering.
