摘要
1990年3月对青岛市崂山水库土坝43m高程以上护坡检查发现,上游坡发生变形,有些点凸,有些点凹,山东省水利科学研究所进行勘察试验分析,认为上游坡变形主要由反滤层变形引起的,这是土坝老化的必然结果。
In March 1990, deformation of the upstream face of the Laoshan Earth Dam above el.43m was observed. Subsidence took place at some points while upheaval occurred at others. Further investigation, which was carried out by Shandong Research Institute of Water Conservancy, showed that deformation happened in the protective filter of the dam. Analysis indicated that deformation of the filter was due to ageing, and this caused the deformation of the upstream face of the dam.
