摘要
采用具有高信息密度的分布式光纤温度传感测量系统进行土石坝渗漏监测技术研究 .经过理论研究和室内、现场试验 ,已取得了初步研究成果 .实践表明 ,该传感系统可以埋置于防渗体的下游排水或反滤层内 ,不会因机械施工而损伤 ,具有施工干扰小 ,抗电磁干扰等特点 ,系统测量精度能满足工程应用的要求 .该项测量技术还可用于混凝土坝的温度场测量 .
The technology of distributed fiber optic temperature measurement offers the possibility to monitor the leakage of embankment dams. This paper describes its principle and experimental results obtained by German experts. It is revealed that this technology can effectively perform leakage monitoring of embankment dams and has the advantage of distributed measurement with high accuracy and magnetic resistance. The installation of optic fiber has little interference to dam construction. This technology can also be used in the temperature monitoring of concrete dams.
