Abstract：The rheological stress recovery method is a new geostress measurement method especially appropriate for deep soft rock.According to this method,the pressure transducers are embedded into the boreholes of surrounding rock.The geostress of surrounding rock can be obtained by analyzing the measured pressure.In order to know the measuring properties of transducers in deep rheological rock mass,the two-dimensional plane strain problem of transcoder embedded in rock mass is discussed.The analytical solutions of stress distribution of transducer are deduced by assuming rock mass satisfying three-parameter solid model and Burgers model.Then,the influence of setting time of slurry,the mechanical property of slurry and the viscoelastic parameters of rock mass on the measured stress of transducer is investigated by parameters analysis.
