摘要
某水库紧靠京沪铁路和国道,为中型水库,地理位置较为重要。该水库自建成蓄水以来,在桩号0+650附近,下游平台坝基测压管水位高出理论值2～3m,出现高水位异常,且长期不下,直接危及坝体安全。为分析该处水位异常的原因,采用综合工程物探的方法,对该处坝基及其下游平台、滩地,进行渗漏状况探测,查明了该处水位异常的原因。
A reservoir is close to the Jing-Hu railway and national highway.It is medium size and important in terms of its geographic location.Since it was built and began to store water,high water level anomaly has occurred near pile No.0＋650,as shown by water level of pressure-testing pipe at downstream platform dam foundation being 2-3m above theoretical value.This high level has existed for a long time and directly endangered the safety of dam.To analyze the cause of the anomalous water level,comprehensive engineering geophysical method has been applied to detection of dam foundation at the spot as well as its downstream platform and bottomland for checking leaks.
