SYSTEMATIC STRESS TEST BASED BACK ANALYSIS OF STRESS DIS TRIBUTION IN SLOPE

The exploration adits w all stress f ie ld o f one eng ineer ing slope w as system ically tested, adopting the stress restoringmethod w ith simplicity, exped it iousness and economy. Accord ing to test resu l,t the slope stress fie ld w as back- analyzed by FLAC2D. The resu lt ind icated that the slope stress field had dist inct zonation in depth. The curve of stress magn itude in depth had typical hump character istic, w hich corresponds to the theoretical analysis. The outcome is of sign ificance to exam ine the deformation, crack ing and re lie f o f the slope.
