摘要: 阐述了新丰江大坝7号支墩扬压力测点运行情况,重点对该坝段扬压力偏高的成因进行分析,认为引起扬压力偏高的原因是坝基存在局部渗流通道,但不致影响支墩抗滑稳定,并在原扬压力孔附近新设监测孔进行验证。
Abstract: The paper introduced the operation of monitoring points for uplift pressure at the buttress No.7 of Xinfengjiang dam and analysed the cause reasons for high uplift pressure. Analysis result showed that the local seepage passage was the main reason. Fortunately, it didn’t exert adverse influence on stability against sliding. Further, new monitoring holes were set around for check.
