| Abstract_FL | Based on Terzaghi-Rendulic's axisymmetric consolidation theory,a radial consolidation coefficient calculation method is pro-posed,and a calculation formula is provided,followed by experimental verification.Firstly,the calculation formula of the radial consolida-tion coefficient was derived based on the relationship between radial consolidation degree and time factor.Then,using the GDS consolidation test system,radial drainage consolidation tests under different consolidation pressures were conducted,and displacement-time curves were obtained.Finally,the calculation method proposed in this paper was used to calculate the radial consolidation coefficient under various con-solidation pressures,and the theoretical solutions were compared with experimental data.The results indicate that the computational method proposed in this paper is feasible and can accurately predict the time-dependent displacement of samples undergoing radial drainage consoli-dation. |
