The present invention provides an intelligent construction control method, apparatus, and system for splitting jet grouting mixing piles, relating to geotechnical engineering. The method includes receiving real-time perception information from a construction information self-perception system, which includes drilling depth, drilling rig output power, drill bit torque, drill rod axial force, and pore water pressure of the drill bit. This information is input into a trained machine-learning model for stratum information, establishing a nonlinear implicit correspondence relationship between the perception information and construction stratum conditions, and outputting real-time stratum state information. The real-time stratum state information is then input into a trained self-matching machine-learning model for optimal construction parameters, establishing a nonlinear implicit correspondence relationship between the stratum state information and optimal construction parameters, and outputting current optimal construction parameters. This invention enables real-time intelligent inversion of stratum information and dynamic self-optimization control of construction parameters.

A method and system for advanced detection and optimization of tunnel resistivity based on depth resolution. The method includes integrating all acquired electrode measurement data into comprehensive set, calculating its model resolution matrix, and selecting plurality of electrode measurement data from comprehensive set to form initial set; adding measurement data of electrodes that are not in initial set to initial set to form plurality of temporary subsets; calculating depth resolution balance goodness function of temporary subset according to model resolution matrix, selecting temporary subset with optimal value of depth resolution balance goodness function as new initial set, and determining whether average relative model resolution of initial set meets optimization requirements; if requirements are not met, continuously updating temporary subset, otherwise outputting initial set; determining number and position of tunnel face measurement electrodes according to updated initial set, and obtaining effective observation mode of advanced detection of optimized borehole resistivity.

A magnetostriction-based vibration suppression apparatus for a steel pipe of a power transmission tower includes a lantern ring, four spoiler cups, and two control boxes; the lantern ring is fixedly sleeved on the steel pipe; mouths of the spoiler cups face outwards, and bottoms thereof are hinged on the lantern ring; the four spoiler cups are squarely distributed; and the two control boxes are symmetrically and fixedly mounted on the lantern ring; the control boxes are arranged as follows: the spoiler cups are arranged in pairs as a group, and each control box is arranged between two spoiler cups; each control box is provided therein with two groups of inerter units corresponding one-to-one to the spoiler cups. The vortex is avoided using a structure such as a spoiler cup, and the vibration kinetic energy of the steel pipe is consumed, thereby achieving an effective vibration reduction effect.
