Abstract: Guanzhong Basin is the ancient birthplace of Chinese civilization, with a rich cultural heritage and brilliant ancient ruins, but these ancient ruins were buried underground mostly and have limited ornamental value and quality, restricting the creation of historical and cultural tourism brands with world influence. Taking the world-famous Maoling Mausoleum as a detection area, the drone aerial survey, ground survey, high-density electrical method, geological radar, high-precision magnetic survey and microgravity nondestructive detection were used to detect the Mausoleum accurately. The underground palace is about 30~40m deep from the horizontal plane and is shaped like a cuboid. It is about 100m long from east to west and about 60m wide from north to south. The underground palace is almost intact and has not collapsed yet. The location and depth of the South, East, and North Tomb passages are almost consistent with archaeological drilling detection. On this basis, using the 3D Max software platform, etc., the micro-movie of "Detecting the underground ruins Emperor Wu of Han at Xi'an-Maoling" has been produced, which virtually reproduced the majestic scale of Emperor's Mausoleum Palace and the shape of the underground palace. It introduces the structure, landscape and era and geographical background, which will greatly enhance the quality of tourism products.
