摘　　要：新疆和田影剧院平面造型宛如一朵含苞欲放玫瑰花,平面形状不规整。观众厅为跨度约30m,高度约为17～20m的大空间;主舞台为宽度20m,层高28.3m的大空间;观众门厅中空部分为直径18m,层高17m的圆形空间。由于结构空旷,跨度大,楼层错落不齐,平面形状不规则造成柱网不整齐,楼座看台悬挑较大,给结构设计造成一定难度。结构设计时利用楼梯间和建筑隔墙设置钢筋混凝土剪力墙,增大结构抗侧刚度和扭转刚度,增强结构抗震能力。屋顶大跨梁施加预应力以减少梁的扰度和裂缝宽度。楼座挑台采用较经济的悬挑刚架方案。人流密集区域周边竖向构件采用中震弹性设计,使其拥有更高的抗震性能。Plane modeling of Hetian Theatre in the Xinjiang Uygur Auto. Region like a rose, its flat shape is irregular. The auditorium is a large space which span is about 30m and the height of about 17 - 20m. The main stage is a large space which width is about 20m and the height of 28.3m. The hollow portion of the audience hall is a circular space which diameter is 18m and the height of 17m. For improving seismic capacity, the reinforced concrete shear wall is setup in the position of stairwell and the building wall to increase the lateral stiffness and torsional stiffness. By applying prestress technology to the large span roof beams reduce deflection and crack width of the beams. For the overhang seats design, the structure was deisgned with more economical cantilever frame structure. To improve the seismic performance of vertical component in the areas of population center, elastic design is chosen under intermediate earthquake.
