摘要
现代土木工程要求沉降观测要做到高效率、高精度、低成本,甚至自动化、信息化,但传统光学水准测量难以满足要求,静力水准系统的推广应用势在必行。在简要阐述静力水准测量技术发展状况基础上,以自整平直读式静力水准仪为例,介绍其工作原理,分析静力水准仪的优势与特点,并引用一个工程实例加以说明验证,同时指出目前静力水准仪存在的不足与缺点,提出静力水准系统应用研究的发展方向。
In modern civil engineering field,settlement observation is required to be of high efficiency and accuracy,even intelligent and informatization with low-cost. Obviously,the traditional optical leveling measurement can＇t meet the demands,so it is imperative to generalize the use of hydrostatic leveling system. Firstly,the development status of hydrostatic leveling technique was stated briefly. Secondly,focus on the direct-reading hydrostatic leveling instrument,its working principle was presented and its advantages were analyzed and validated with a engineering example. Finally,the existing shortcomings of current hydrostatic leveling instruments were summarized,and the applied research direction of hydrostatic leveling system was put forward in pertinency.
