体育场坐落在咸阳市西北部的北塬文体功能区内、拥有约34公顷湖面景观的双照湖公园西岸，规划设计充分利用场地滨湖的优势，延伸二层人行平台，将奥体园区与公园联系起来，并在湖面上设计了观光塔（赛时兼有火炬塔功能）。

Xianyang Olympic Sport Center is located at Beiyuan culture and sport district, the West bank of 34 hectares in Shuangzhao lake area. When the designer was working on the planning design, they took special advantage of the lake landscape. They extended the second floor of the pedestrian platform into the park, to link the Olympic Center park to lake park. A sight view tower was built on the lake ( it is also a torch tower).

体育场的建筑造型以“鼎”为形，在形态处理上融入高台、重檐、柱廊等古典特征，罩棚的幕墙系统取秦代铠甲的意象。同时秦人崇法也给了设计启发，体育场采用了圆形平屋面罩棚，从钢结构桁架到建筑构件力求标准化建造，构造体系的逻辑简洁，构成强秩序感，一定程度也提高了施工效率，有利于平衡工程造价。

The concept design of the stadium, comes from a important traditional instrument called “Ding” and its form inherit the construction style of Qin dynasty, which is concise and powerful, reflecting the unique characteristics of sport architecture. The architecture elements like high platform, double eaves and colonnades were reused in the stadium with the implementation of modern techniques. The facade of the stadium utilizes elements taken from the armor of the Qin dynasty. The design also inspired by the “legalism” philosophy, is shown at the standardized flat and round roof awning, steel trusses and many other building components. These standards add logic to the construction system making it concise and orderly and at the same time improve the construction efficiency and reduce construction costs.

体育场外表皮系统在设计创意的基础上，结合消防排烟的影响，表皮保持一定的透空率，采用玻璃和铝板两种材质，形成强烈独特的视觉效果，同时形成内部丰富的空间光影。

Based on the concept idea and the need of fire control and smoke discharge, the design of the stadium’s facade keeps an amount of space for ventilation purposes, by the use of glass and aluminum, two materials where a semi-transparent skin system can be created by shifting and altering its shape.

The canopy of the stadium is a steel circular full cover, which will guarantee that all of the stands are within the shelter area and provide a comfortable game watching environment. The main structure of the stadium is the space pipe truss structure system. Since there is a need to save the construction time to ensure the provincial games would be held on time, standardized design and installation were highly regarded and the amount of steel and bar system were optimize as well.

体育场设置二层平台，将观众人流由体育场四面的临街集散广场通过大台阶直接引导至二层观众平台，从而平层进入体育场的看台区，或由外部楼梯上至上层观众看台。观众在赛时期间通过更简单的隔离管理，不会与主要在首层活动的运动员、技术官员、媒体、贵宾等赛事运行流线产生交叉，保障赛事管理的便捷和有序，同时结合完善的无障碍设计，保障残障人员使用便捷。

The stadium has a second-floor platform to guide the audience exchange from the Olympic sports plaza to the stadium’s stands; additionally the upper stands can be accessed directly by conveniently located stairs.
