[摘要]柬埔寨國家體育場東西對稱設(shè)置月牙形罩棚,最大懸挑跨度約65m,南北設(shè)人字形索塔,塔高99m,建筑形式新穎。罩棚體系選用了新型的斜拉-張力結(jié)構(gòu)體系,針對該新型結(jié)構(gòu)體系進行了形狀優(yōu)化和構(gòu)件方案比選,并研究了施工方案的可行性以及結(jié)構(gòu)抗連續(xù)倒塌能力;對索塔結(jié)構(gòu)進行了塔型優(yōu)化、材料及截面形式比選,對其基礎(chǔ)以及背索方案進行了優(yōu)化;根據(jù)環(huán)梁、斜柱受力特點,進行了環(huán)梁、斜柱結(jié)構(gòu)選型;最后討論了看臺結(jié)構(gòu)選型和優(yōu)化。優(yōu)化后的結(jié)構(gòu)方案滿足建筑使用及效果要求,結(jié)構(gòu)性能優(yōu)良。

Abstract:Morodok Techo National Stadium in the Kingdom of Cambodia is equipped with crescent-shaped canopy symmetrically from the east to the west, with a maximum cantilever span of about 65m, and a herringbone cable tower is set up from the north to the south, with a height of 99m and a novel architectural form. A new type of cable-stayed tensile structure system was selected for the canopy system. The shape optimization and component scheme comparison were carried out for the new structural system, and the feasibility of the construction scheme and the progressive collapse resistance of the structure were studied. The tower type optimization, material and cross-section form comparison were carried out for the cable tower structure, and the foundation and back cable structural scheme were optimized. According to the mechanical features of ring beams and inclined columns, the structural system selection of ring beams and inclined columns was carried out. Finally, the selection and optimization of stand structure were discussed. The optimized structural scheme met the requirements of building use and effect, and the structural performance was excellent.
Keywords:Morodok Techo National Stadium in the Kingdom of Cambodia; canopy; selection of structural system; cable-stayed tensile structure
