Combined with practical experiences and structural features of composite structure buildings wall cracks caused by uneven settlement of foundation and temperature stress are briefly analyzed,at the same time some practicable prevention and treatment measures are proposed in order to reduce the production of cracks to ensure appearance quality and service function of structure.

The influences on deformation and internal force of the superstructure caused by ground unequal settlement;

Application study of treating differential settlement of subgrade with geocell;

With an example of a project,this paper introduce and analysis the causes of buildings uneven foundation subsidence in subsidence surveying.
