Karst Geological Exploration and Analysis of Renovation Plans for Tunnel Engineering
Geological exploration is a type of geophysical exploration technology,which infers the condition of un-derground rock strata by measuring the travel speed and reflection of seismic waves in underground rock strata.In order to accurately explore the stratum environment of the construction area,this studies uses a method of combin-ing drilling and geophysical exploration to explore the geology of the karst area,and based on exploration data,it uses the numerical simulation method to predict key construction parameters,which provides reference for engi-neering planning and construction.This study conducts a comprehensive comparison of drilling and geophysical re-sults,obtains the more detailed geological features of the region,and analyzes the simulated value and measured value of column depth and axial force during pile foundation construction.Analysis results indicate that the mini-mum error is only 0.21 kN,and that the average error is 5.17 kN,which further confirms the feasibility of the ex-ploration method and the numerical prediction method proposed in the study.
