| Abstract: | Four large concrete foundations for granite sawing machines have failed in a few hundred hours of normal service.Severe cracks developed due to excessive vibration.The over_vibration of whole system,in turn,caused unsafety for the sawing operation.In order to investigate failure causes and to restore the function of foundations,field test and analysis are carried out.Based on test results and dynamic analysis of the foundations,the causes of the faiure are carefully identified.After field tests and theoretical analyses,a multi_approaches repair strategy is implemented to restore the function of the foundations,in particular in relation to excessive cracks and over_vibrations.It is proven that the repair strategy implementation is successful. |
