Integrated geophysical exploration of the Wei concubine in the Tang-dynasty Zhao Mausoleum

Tomb of Wei Concubine is the nearest to Zhao mausoleum and the highest level in all the Tomb in Zhao Mausoleum,as also, it is the only construction tomb in Mountain of the Tang Dynasty that has been compouded,so,it is improtant to research and protect Tang-dynasty mausoleum.We survey the tomb of the Wei concubine with uav lidar survey, ground high-precision gravity and magnetic survey, high-density electrical survey, GPR and soil radon gas survey for evaluating the results. Ground high precision gravity and magnetic survey combined with soil radon measurement can effectively delineate the plane position of underground place. The high density electric method accurately delineates the space position under ground. The GPR has clearly detected the fine structure of the tomb with a resolution of up to sub-meter level, These resoults provide valuable information for exploration of Zhao Mausoleum's underground palace in the future.
