Abstract: A super high-rise building in Lanzhou is the pioneer at several apsects that the total height is266 m with 56 layers,the maximum pressure of core tube base reaches 1160 k Pa,the exvacation depth is19. 0m and the maximum excavtion depth is 25. 3m. The building is founded in the Tertiary sandstone layer naturally,therefroe fully understand and appraisal of the properties of the layer on bearing capacity,deformation is significant to perform the feasibility study. Comprehensive testing and study of the ground shoud be carried out prior to the design of the foundation of the high-rise building which would provide the sufficient scientific theoretical basis for foundation design.
