在现代测量领域内,测量仪器选择的依据和测量项目精度要求有关,项目精度要求越高预示着对测量仪器的精度指标要求越高。如何利用常规仪器完成高精度要求的项目是测量界一直关心的难题。本文以桥梁挠度监测为例,提出一种新的实时监测方法,并从理论和试验模拟证明了该方法的可行性。为今后类似工程方案设计的制作提供新的思路,具有一定的现实指导意义和应用价值。
In the field of modern surveying, the basis for the selection of measuring instruments is related to the accuracy requirements of the surveying items. The higher the project accuracy requirements, the higher the requirements on the accuracy indexes of measuring instruments. How to use the conventional instruments to complete high-precision requirements of the project is the measurement community has always been concerned about the problem. Taking bridge deflection monitoring as an example, this paper proposes a new real-time monitoring method and proves the feasibility of the method from theoretical and experimental simulations. It will provide some new ideas for the design of similar projects in the future, which will be of practical significance and value.
