1. A method for determining a consistency coefficient of a power-law cement grout, comprising the following steps:
determining a water-cement ratio ω of the power-law cement grout, wherein the water-cement ratio ω of the power-law cement grout is expressed by the following formula:, ω
   =
   
    
     m
     w
    
    
     m
     c
    
   
  
  ,
  
   m
   w, represents a mass of water required to prepare the power-law cement grout, and mc represents a mass of cement required to prepare the power-law cement grout;
determining, according to engineering practice requirements, a time t required to determine the consistency coefficient c of the power-law cement grout; and
obtaining the consistency coefficient c of the power-law cement grout based on a quantitative change rule between a comprehensive effect of the water-cement ratio ω and the time t and an influential effect of the comprehensive effect on the consistency coefficient c of the power-law cement grout, wherein the consistency coefficient c is expressed by the following formula:
c=0.0387ω−6.610e(0.000270+0.000141ω)t, e represents a base of natural logarithm, and ω∈(0.50, 0.75).
