电子水准仪和Excel在+255沉降观测中的应用

电子水准仪提高了水准测量的外业速度,同时也提高了测量数据的精度、效率;减轻了测量外业人员的劳动强度。在内业处理时,使用Excel做处理,快速准确的计算出各个观测点在不同观测日期时的高程值,并且通过Excel计算出各个观测的沉降值。根据各个观测点高程值、累计沉降值通过Excel做出各个点的沉降与时间关系图,无需人工作图。根据做出的沉降时间关系图,对沉降做出分析。

Application of Electronic Level and Excel in ＋255 Settlement Observation

The electronic level improves the outside leveling speed, also improves the accuracy and efficiency of the measurement data, and reduces the labor intensity in outside measurement. In the inside processing, it can quickly and accurately calculate the elevation values of various observation points on different observed dates by Excel, and through Excel can calculate the settlement value of each observation. According to the elevation values of each observation point and the cumulative value of the settlement, the Excel can help make the diagram about the relationship between settlement of various points and the time, without people drawing. According to the diagram of settlement and time, the settlement can be analyzed.
