The tests focused on the analysis of the different storage forms of packed sand under the condition of indoor simulation for example double-layer storage form three layer storage form single arch storage form double arch storage form and so on and the changing rule of the load and settlement under the same condition of load pressure was tested which summed up the foundation uneven settlement.The results show that under the double arch storage form the changing rule of load and settlement and the uneven settlement of the foundation...
