Abstract: A method and system for real-time prediction of jamming in TBM tunneling. The method includes: (1) obtaining actually measured TSP physical property parameters by applying a TSP method; (2) analyzing value ranges and change trends of the TSP physical property parameters obtained in real time; (3) establishing a TSP physical property parameter sample database of a TBM tunnel; (4) establishing a mapping relationship between TSP physical property parameters and occurrence or not of jamming; (5) establishing a mapping relationship between time sequence values of tunneling parameters and occurrence or not of jamming; and (6) forecasting a TBM jamming risk in real time, and storing reliable data into the TSP physical property parameter sample database. The method and system can effectively obtain a state of surrounding rocks in time, thereby providing real-time forecasting of TBM tunneling jamming, avoiding occurrence of accidents to some extent, and improving the TBM tunneling efficiency.

Abstract: A three-dimensional imaging method and system for surface comprehensive geophysical prospecting, the method includes: acquiring detection data of a plurality of two-dimensional profiles of a surface detection site; forming two-dimensional profile resistivity data by geophysical inversion of the detection data; performing three-dimensional coordinate conversion on the two-dimensional profile resistivity data to obtain resistivity data of a three-dimensional coordinate system; and converting the resistivity data of the three-dimensional coordinate system into a three-dimensional model by using a Kriging interpolation method.

Abstract: A kind of hygienical shoes with mobile magnet piece, which can produce the static and dynamic magnet field for the sole of foot of human body, especially it can carry out the magnetotherapy for the sole of foot with take advantage of the static and dynamic magnet field generated respectively at sole when human body stops and walks. Wherein the shoe sole includes a lower sole and a insole covering on the upper surface of the lower sole; the grooves is set on the upper surface of insole, and the mobile magnet pieces is provided on the bottom of groove. When the shoes according to the present invention are wore on foot for walking, as the foot lift up and fall down, the front and back portions of grooves will change their relative position repeatedly, and the magnet pieces in the grooves will move fore-and-aft depending on the obliquity of the bottom of groove under the effect of gravity, which result in the movement of magnet field, i.e. the dynamic magnet field.
