| Causes of Karst Groundwater Damage to the Zengpiyan Ruins of Guilin and the Prevention and Control Countermeasures |
| Since the beginning of the trial excavation of the Zengpiyan Ruins in Guilin in1973, large quantities of precious material objects were unearthed, such as skeletons of the ancients, fire ponds, tombs, stone implements, clam tools and animal or plant fossils. These achievements have made the Zengpiyan Ruins one of the important ruins of the new stone implement times, which was therefore put on the list of the national key preservation units of cultural relics. During the flood season of 1994, the ruins were soaked in water, which resulted in the collapse of the exploratory shaft beam as well as some other serious damages. Some rescue and protection measures were taken, which, however, failed to eliminate the hidden trouble caused by rapid falling and rising of underground water during the rainy season. Based on an investigation and analysis of the relevant data, the authors put forward the following opinions: Karst channels are extensively developed in limestone in the lower part of the cultural accumulated soil layer, and the hydrodynamic action caused by rising and falling of the underground water level during the alternate high flow and dry seasons results in the softening of the cultural soil layer, the erosion of soil grains, the formation of soil holes and the eventual collapse and sinking of the cultural bed. In view of such a situation, we should find out such large-scale water-conduit media as underground karst caves, channels, groundwater rivers and large karst fissures and try to block up them so as to prevent the damage to the cultural bed caused by the rapid rising and falling of the underground water during the flood period. |
