Notes:
The center hole deformation test of rigid bearing plate is an important method forunderstanding deformation properties of deep weak rock mass. According to the center holedeformation test of rigid bearing plate in dam zone of Dagangshan hydropower station, this paperdetailedly recommends test method of this experiment, and the settlement deformation formula ofdeep rock mass under circular rigid bearing plate is deduced, which could be used to calculatedeformation modulus and equivalence deformation modulus of different deep rock mass at testpoints. According to curves of depth-deformation under different pressures at test points in dam zone,we have analyzed deformation characteristics of deep weak rock mass. By the center hole deformationtest of rigid bearing plate, stratum properties in dam zone of Dagangshan hydropower station could beunderstood further, and it provides important references for the study of creep speciality of weak rockmass in dam zone
