The Study On Engineering Application Of Supporting System For Foundation Pit In Fill Site

The deepening of the urban construction, the fill site gradually becomesengineering construction land.The problem needed to study is therefore that theevaluation of engineering properties of miscellaneous fill, the mechanism offoundation pit supporting structure stress, deformation and failure mode.Basing on the comprehensive evaluation of filling site engineering characteristicsand the actual project, the filling soil field mechanism of the pile anchor supporting isanalysised with numerical, the following aspects: carried on the summary and theevaluation of engineering properties of filled soil, proposed the present problem fillingsite survey and solution, emphatically summarized the determination of filled soilstrength parameters; Analysis of the filling soil field under different working conditionof foundation pit horizontal deformation, vertical deformation, axial force, anchorsupporting pile bending moment and horizontal deformation and potential slip surfaceof the pile and anchor system; Combining with the theoretical guidance, the problemsof geological survey, localized intensity parameter selection, support design,construction and deformation monitoring in detail are studied for the actual filling soilfield slope from engineering survey, which provides a certain reference to fill soil field.
