Observation and Analysis of Settlements of Oil Tanks on High Compressive Saturated Soft Clay

This paper summarizes the experiences obtained in the design and construction of oil tank foundations on untreated high compressive saturated soft clay. Through the study and analysis of the various data collected from long-term observation, the author has proposed a number of suggestions on the designing of the foundation of oil tanks, the calculation of the deformation of tank floors, allowable differential settlement and the spacing of tanks. In addition, the paper also gives an account of the behaviour of the site and the deformation of tanks resulting from the Tangshan Earthquake
