| Abstract: | This paper analyzed why stability of gravity retaining wall in cutting section ot exlstmg tree was reduced, and introduced the principle how slop cutting and load shedding may improve the stability coefficient. Then, according to defect inspection, some practical approaches to improve the coefficient were proposed, with the drainage and reinforcement measures on condition of wall back under water, which have practical significance to maintenance of such retaining wall. |
