The invention discloses a method for predicting unfavorable formations based on shield tunneling parameters, comprising the following steps: S1, data collection; S2, determining the specific energy of shield tunneling: the energy required for shield tunneling per unit volume; S3, determining the correction ratio Can predict the model, SM=K p log e (s×L(v n ))+C; S4. Input the obtained tunneling parameters into the specific energy prediction model to obtain the corrected specific energy value of the shield tunneling formation, and judge whether it is a poor rock formation; S5. According to the output corrected specific energy value, judge the shield tunneling For the method of crossing the boulder stratum, when the corrected specific energy value is less than 1, the method of directly pushing the shield through the boulder stratum is adopted; when the corrected specific energy value continues to be greater than 1.5, the boulder needs to be broken, which is divided into ground treatment and In-hole processing; the invention only uses the shield tunneling parameters recorded in real time by the PDV data acquisition system to accurately judge the existence of boulders in the stratum through which the shield tunnels, with simple operation and low cost, effectively avoiding missed inspections, and ensuring the safety of shield tunneling .
