Experimental study of 3d geomechanical model on global stability of an arch dam under complex geological condition

Aiming at the complex geological structure of a high arch dam in dam site area,there are many different weak structural planes in rock mass of the dam foundation such as fault,lamprophyre,inner layer extrusion zone,deep cracks,which are disadvantageous to the stability of the dam foundation and abutment.The whole process of the arch dam and abutments from loading to failure are studied by three dimensional geomechanical model test.The model considers various factors influencing the stabilities o...
