| Abstract: | A modified oblique bracing supporting system was used in supporting construction of foundation pit for a shopping mall in Jinan city,which occupies more than 50000 m~2.The oblique bracing supporting system,which is different from normal pattern,includes supporting piles,oblique bracing constructions, vertical pillars and struts.Through the analysis of explicit finite difference numerical calculation with FLAC~(3D) program,considering the results of in-situ monitoring of supporting piles,some conclusions are... |
