Based on the structure-foundation-soil interaction，the model experiment is used to study the tall and low building with thick raft foundation. The distribution regularities of foundation settlement，the compression settlement of soil mass，contact pressure，interaction of tall and low building and deformation control are summarized. The test result shows that the maximal value of the interaction regions for the tall building and low building is 3 spans. the major thickness of compressed layer for the tall building is 0.6 times foundation width，the integral flexure of the tall building is decided by it¢s structural rigidity and load，the inclination of the tall building increase with the increase of the differential load. So the inclination may be the important deformation control for the complex high-rise building.
