On treatment of deep soft foundation under retaining walls with grid layout mixing piles

Combining with the retaining wall design in the water system works at Beitang District of Tianjin,the study explores the treatment scheme for the deep soft foundation under the retaining walls,compares the calculation of the loading capacity of the mixing piles and the composite foundation,and analyzes the influence of the mixing pile layout on the anti-sliding and stability of the retaining walls,so as to accumulate relative experience and direct similar projects.
