长期以来，沉降观测的资料整理、图件绘制、报告编写等工作均由手工完成，工作量大。“沉降观测信息系统”的开发，不但有效地解决了建筑物沉降观测资料的存贮、管理和查询应用问题，也大大提高了沉降观测内业工作的效率。本文介绍了该系统的设计开发思路、特点及其应用情况。 For a long time, the data of settlement observation, drawing, report writing and other work are done by hand, with heavy workload. The development of the “Subsidence Observation Information System” not only effectively solves the problem of storing, managing and querying the data of subsidence observation of buildings, but also greatly improves the efficiency of the subsidence observation work. This article introduces the design and development of the system ideas, characteristics and applications.
