In the architectural design, simple geometric sphere with unique recognition is adopted, to-gether with the classic proportion of patterns and texture. However, it is undoubtedly necessary to enlarge such a refined and figurative shape into a public building of 90 meters in diameter and 46 meters in height, which has brought huge challenges to the designer. How to reflect the pat-tern texture and form proportion but also to avoid concretization is the first biggest challenge faced by the designer. Integrate modern design techniques into this traditional body, and leave a contemporary archi-tecture with strong ethnic characteristics to the local people has become the designer’s design purposes.

After thinking over and over again, the designers abandoned the “simple” and expensive solu-tion of the traditional metal curtain wall to realize the geometric texture of the dome. Through continuous efforts, The cross-section steel beams are welded to each other to “weave” the overall spatial structure of the dome “texture,” similar to the “Bird’s Nest” structure of the National Olympic Sports Center. Shell structure, curtain wall structure and curtain wall texture are com-bined into one, saving a lot of cost. As a result, the powerful permeability shell inside and outside the entire facade makes it possible to change the building from the “impervious” to the top of the “all through”, plus the facade “snow white” color selection, the dome shape of the original statue becomes abstraction. This will not only achieve the overall effect of the building, but also display the magnificent charm and immortality of the heavy steel structure. The building and the struc-ture are seamless, unique and beautiful with strong visual impact and fully reflect the beauty of natural harmony.

大剧院总高度约 46 米，为保持穹顶高度的同时充分利用空间，将大剧院内部主体向上抬高一层。下部用来设置贵宾厅和大面积装卸场地以满足功能需求。剧场设计容纳 1052 位观众，包括102 个乐池的可活动座椅。观众厅分为池座和楼座两部分，池座可容纳 860 位观众，楼座可容纳 192 位观众。舞台是整个剧场的核心，采用国际上通行的“品”字形布局并拥有一个由两部分组成面积为120平方米的乐池，可容纳100人的交响乐队。中心演出区域的舞台则拥有侧车台、15米见方的大型车台、冰车台、芭蕾舞台、直径为14米的行走式转台、五块双层电动升降舞台等功能。这些功能舞台通过电脑控制可以升降、旋转和移动，能够完成复杂的剧幕场景变换，充分满足了音乐剧、歌剧、芭蕾、戏剧和综合文艺演出的不同需求。
Grand Theater has the total height of about 46 meters, in order to maintain the dome height while making full use of space, the Grand Theater main body is one floor level up. The lower part is used to set up VIP lounges and large area loading and unloading venues to meet the functional needs. The theater is designed to accommodate 1,052 spectators, including 102 active seats in the pool. Auditorium is divided into the pool seat and the floor seat, pool seat can accommodate 860 people, and the floor seat can accommodate 192 spectators to watch the show. Stage is the core of the entire theater, using internationally accepted a Chinese Character as “品” shaped stage. And has a two-part area of 120 square meters of music pool, can accommodate symphony orchestra with 100 people. Center performance area stage has a car side, 15 meters square large stage plat-form, ballet stage, walking turntable with diameter of 14 meters, five double electric lift stage and other functions. These functional stages can be controlled by the computer, to be raised, rotated and moved to complete the complex screen scene transformation, and fully meet the different needs of musicals, operas, ballet, drama and theatrical performances.

In terms of vision design, the farthest place of the floor seat is 26 meters less than 33 meters, with downward tilt angle of 20 degrees, the pool seat depression point is less than 35 degrees, dis-play angle is controllable, pool seat, floor seat subject to the stage angle control, view the audito-rium from the stage center, the angle is greater than 80 degrees, the first surface light bridge an-gle between the table is subject to 50 degrees light control. In acoustical design, the design of dou-ble walls, acoustic mats meet acoustic isolation. Air conditioning and ventilation systems are de-signed with mute operation. This results in a PNC value (ideal noise level) of noise control of this scheme reaches 15 or lower. The design is a combination of two completely different building types – a concert hall and a theater with a stage. The design uses a special orchestra enclosure. When performing an orchestral show, it’s easy to move it out of place to split the stage part, translating the two spaces into one space. At the same time, lift the pool to the same level of the stage, forming a platform at the stage for the band to play.
