Title : A Coupled Model for Variation Diagnosis of Hydrological Series and Its Application
Qian, L., , Li, H., , Wang, T., , Wang, Y., , Wang, H.,
Abstract : A hydrological simulation in the Huaihe River Basin (HRB) was investigated using two different models: a coupled land surface hydrological model (CLHMS), and a large-scale hydrological model (LSX-HMS). The NCEP-NCAR reanalysis dataset and observed precipitation data were used as meteorological inputs. The simulation results from both models were compared in terms of flood processes forecasting during high flow periods in the summers of 2003 and 2007, and partial high flow periods in 2000. The co

Title : Time-dependence of Generalized Rheological-compliance and Rheological-modulus About Rock
ZHANG Hailong, , TANG Yang, , REN Ting, , OKUBO Seisuke,
Abstract : Creep deformation and stress relaxation are two properties of rock mass in underground engineering, but in many construction practices, rock mass is neither pure creep deformation nor pure stress relaxation, with stress and strain of rock masses simultaneously changed with time, which is time-dependent, and may ultimately cause failure. It’s hard to explain the phenomenon simply by creep deformation and stress relaxation, so it is a challenge for rock mechanics researchers. To ensure the l
