一种新型水准尺在基坑监测中的研究及应用

Study and Application of a New Level Ruler in Excavation Monitoring

设计一种新型水准尺,利用该水准尺,在完成初始安设后,竖向位移监测过程只需要1名测量人员操作水准仪,即可高效、安全地完成水准测量,且测量精度满足二等水准测量的各项技术要求。该水准尺可有效提升监测人员的安全,提高工作效率,节约人工成本,具有良好的社会与经济效益及推广应用前景。

A new type of level ruler is designed and introduced. With this level ruler,only one surveyor is required to operate the level gauge in the vertical displacement monitoring process after the initial installation,and it can be placed in the appropriate position between the fixed level ruler to complete the level measurement efficiently and safely,and the measurement accuracy meets the technical requirements of second-class level measurement. This level ruler can effectively improve the safety of monitoring personnel,improve work efficiency,save labor cost,which has good social and economic benefits and prospect of popularization and application.
