Hangzhou E-sports Center project adopts various foundation forms such as pile foundations and raft foundations.The YJK software was used to calculate the settlement difference between multiple foundation forms,and strengthening measures for the application of multiple foundation forms in the same building were proposed.For the problem of unbalanced water and soil pressure in the basement with soil covering on three sides and openness on one side,pile foundations were utilized to resist the unbalanced water and soil pressure,and corresponding strengthening measures were put forward.Various anti-floating technologies such as uplift piles,unbonded prestressed anti-floating anchors and drainage and pressure relief were applied in this project.The application of the active anti-floating technology of drainage and pressure relief based on the principle of the communicating vessel greatly reduces the number of anti-floating anchors and achieves good economic effects.For the connection nodes of multi-directional frame beams and inclined columns in the project,circular column caps were adopted to effectively restrain the intersecting frame beams in each direction,and finite element analysis was carried out by using ABAQUS to simulate its mechanical performance,proving the reliability of the connection nodes.Finally,the design of the large-span column-free arc-shaped staircase in the sunken courtyard was introduced,the comfort check was carried out,and the results meet the requirements of the code.
