大坝安全监测行业标准规定用于大坝变形监测的全站仪精度需在1秒级及以上,目前大中型工程中大多采用的是0.5秒级的全站仪。对于中小型工程,采用1秒级全站仪并根据工程的具体情况制定合适的现场测边、测角观测方案,也能达到规范规定的位移量观测精度指标。通过部分中小型混凝土坝及土石坝采用1秒级全站仪工程监测实例,表明采用科学合理的监测方案,1秒级全站仪应用于中小型混凝土坝及土石坝变形监测是可行的。
The dam safety monitoring industry standard stipulates that the total station accuracy for dam deformation monitoring needs to be 1 second and above. At present, the 0.5-second total station is mostly used in large and medium-sized projects. For small and medium-sized projects, the use of 1 second total station and according to the specific circumstances of the project to develop a suitable scene measuring edge, goniometry program, but also to achieve the specifications of the displacement measurement accuracy indicators. Through some small and medium-sized concrete dams and earth-rock dams using 1-second total station engineering monitoring example shows that the use of scientific and reasonable monitoring program, 1 second total station applied to small and medium-sized concrete dams and earth-rock dam deformation monitoring is feasible.
