Design And Analysis Of The Forces Of Retaining Structure With Double-row Piles Of Deep Foundation Pit

This paper summarizes the achievements that have been made in retaining structure with double-row piles and other corresponding retaining structures, and points out their disadvantages, then induces calculating model of retaining structure with double-row piles and compares several design methods. The thesis also applies soil arching to their analysis to retaining structure with double-row piles and, on the basis of former achievements, deduces the function formula that vertical soil arching and horizontal arching made to the retaining structure with double-row piles. Considering the spatial effect of deep foundation pit and the functions of the girth and linking beam on the top of pile, three-dimensional analysis is made for the force situation of retaining structure with double-row piles. The best design is made according to the design and analysis of practical retaining structure with double-row piles and as well as the revision of different programs with PKPM.The influences of many factors on retaining structure with double-row piles have been discussed as well. Through the comparison of numerical results, the general working rules have been summarized, and some valuable results have been achieved, which will be valuable to practical engineering.
