PHYSICAL-MECHANICAL TEST AND MINERAL ANALYSIS OF ROCK FORMING LONGEVITY HILL OF SUMMER PALACE, BEIJING

The Summer Palace in Beijing is one of the world's cultural heritage protection units. Its Longevity Hill is located within the north portion of the Summer Palace. The Hill stands a series of cultural relics. For protection of Longevity Hill and its cultural relics, this paper investigates the characteristics of the hill and rock properties. It is based on the existed documentations of Longevity Hill's geological origin. It measures the rock occurrence and rebound strength at different exposed locations. The physical and mechanical properties include density, tensile strength, compressive strength, shear strength. They are tested in laboratory. The mineral composition and content ratio of the rock at Longevity Hill are obtained using thin-sections, rays test, and SEM tests. The results of experiments and tests can have significance and application because they are the basis for geological research and stone relic protection of Longevity Hill.
