Through cause analysis for filler wall body cracking of a series of uneven foundation frame structure,the safety of building frame structure was determined,reasonable treatment measures were taken pertinently and good result was obtained.

Foundation design on uneven ground;

Uneven ground treatment, especially in hilly country is a difficult problem for geotechnical engineers and designers.

A non-linear FEM model capable of taking into account the load bearing characteristics of the key groove is established to study the settlement and stress of the stilling pool under various working conditions, according to the layout of the stilling pool during construction and the latest geological investigation of the non-uniform foundation information on Baise project.

The paper introduces the kinds and appearing time of wall crack,analyzes its causes form asymmetry settlement of foundation and temperature fluctuation,and introduces prevention and management measures for it to effectively control its fault degree.

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.

Geological examination and testing study in situ reveal that the main cause for the destruction of buildings in Fushan city is the inhomogeneous settlement of ground triggered by fault motion.
