Abstract
The paper deals with a case history of a local foundation failure caused by removing the neighbouring building. Displacement measurements after removing the neighbouring all the working stages at the site. The shape of the deformation curve points to failure after removing the neighbouring old building. The foundation soil is a Moscow sand typical for the large part of the urban Moscow area. It is a poorly graded fine sand of a medium density. Using back analysis for all working stages the peak and residual parameters caused by foundation failure were defined. The ratio of residual to peak value of "0" for a foundation sand corresponds very well to literature sources referring to this type of soil. Numerical model proved that the "Fs" value was satisfactory after the completion of protection works. On the other hand, measured displacement values showed that the displacement gradient mainly dropped to the negligible value.
