Implement and application of the wire alignment system at Xinfengjiang dam;
引张线系统在新丰江大坝的实施及运用
It discussed that the build method of automatic monitoring system for wire alignment in dam.
指出了大坝变形监测系统中自动化监测与人工观测方法的差异,对引张线自动监测系统的构建方法进行了论述;通过分析说明了试图采用双向引张线监测垂直位移尚不可取;分析表明,引张线端点外延将明显降低引张线准直系统的精度,长的引张线应避免采用端点外延布置;采用相对测量方法、配合双金属管标的液体静力水准系统是一种灵活、简便的高精度垂直位移自动化监测系统;分析比较测斜仪和垂线的精度表明,试图利用测斜仪来取代垂线的想法是不可行的。
