Full-depth array inclinometer and deep displacement measurement method

Abstract

The invention provides a full-depth array inclinometer and a deep displacement measurement method, which are used to measure the deep displacement of an inclinometry hole in segments. The inclinometercomprises an inclinometry frame, an inclinometry unit installed in the inclinometry frame and a data collection unit. The inclinometry frame comprises a plurality of rigid sleeves and a plurality ofuniversal joints. The rigid sleeves are connected through the universal joints. The rigid sleeves and the universal joints divide the inclinometry hole into multiple inclinometry segments along the vertical direction. The inclinometry unit comprises a bus and a plurality of sensors. The sensors are connected in series through the bus, and are installed in the rigid sleeves. The data collection unit collects the deformation data of the inclinometry segments at different time through the bus, and calculates the deep displacement of the inclinometry hole according to the deformation data and thelength of the inclinometry segments. Automatic monitoring of deep displacement of an inclinometry hole in a full depth range is realized.

Description

technical field [0001] The invention relates to the technical field of deep displacement measurement of rock mass, and more specifically relates to a full-depth array inclinometer and a deep displacement measurement method. Background technique [0002] Deep displacement monitoring is a common method in geotechnical engineering monitoring and various slope monitoring, which is used to judge the deep sliding surface and deep displacement. The traditional monitoring technology mainly uses manual inclinometers, and the data is sorted out in the industry after segmental and timing measurements. [0003] With the rapid development and application of information technology, the automatic monitoring of deep displacement has been realized by using sensors and other equipment and technology, replacing traditional manual monitoring, which greatly improves the monitoring efficiency and saves a lot of manpower and time. At present, the automatic monitoring of deep displacement mainly a...
