【摘要】：三向測縫計在混凝土面板堆石壩周邊縫監(jiān)測中廣泛應(yīng)用,為優(yōu)化其設(shè)備選型,避免安裝缺陷,以3DM型柔性鋼絲位移計整體式三向測縫計、剛性拉桿位移計整體式三向測縫計、剛性拉桿位移計分體式三向測縫計為例,分析了3DM型三向測縫計在設(shè)備選型、安裝要點及監(jiān)測成果分析等方面的優(yōu)勢。結(jié)果表明,3DM型柔性鋼絲位移計整體式三向測縫計工作原理及計算公式科學(xué)合理,相比分體式等其他類型三向測縫計具有量程大、安裝方便、測量精度高、耐水壓級別高等優(yōu)勢。在工程實施中,應(yīng)注意控制好安裝過程中的重要環(huán)節(jié),避免各項安裝缺陷。工程實踐證明,通過對3DM型柔性鋼絲位移計整體式三向測縫計的監(jiān)測結(jié)果進行科學(xué)合理地分析處理,可以正確反映大壩周邊縫的變化情況,為大壩的安全評價提供科學(xué)合理的評判依據(jù)。
[Abstract]:In order to optimize the equipment selection and avoid installation defects, the 3DM flexible steel wire displacement meter and the rigid pull rod displacement meter are used as integral three direction jointmeter, in order to optimize the equipment selection and avoid the installation defects, the three-direction jointmeter is widely used in the monitoring of the peripheral joints of concrete face rockfill dam. As an example, the advantages of 3DM type three-way joint gauge in equipment selection, installation and monitoring results are analyzed. The results show that the working principle and calculation formula of the integral three-direction jointmeter for flexible steel wire displacement meter are scientific and reasonable. Compared with other types of three-way joint gauge such as split type, it has the advantages of large measuring range, convenient installation, high measuring precision and high water pressure resistance. In the project implementation, attention should be paid to control the important links in the installation process to avoid the installation defects. It has been proved by engineering practice that the monitoring results of 3DM flexible steel wire displacement meter can accurately reflect the variation of the peripheral joints of the dam by scientifically and reasonably analyzing and processing the monitoring results of the integral three-direction jointmeter. It provides a scientific and reasonable basis for dam safety evaluation.
