| Abstract: | Combining the indoor test data,the monitoring data of dams,and the computed results of deformation and stresses,several problems occurred in construction of current earth-rock dams with asphalt-concrete impervious layer are analyzed and discussed. At first,the experimental conditions of the hydro-technical asphalt concrete test samples,such as the moulding method,loading rate and test temperature are analyzed; the default of static side pressure coefficient K0 of asphalt-concrete core in the present design ... |
