Abstract

The invention discloses a high-speed railway structure settlement monitoring device and a high-speed railway structure settlement monitoring method. In the device, a seal cover is arranged on the upper part of a liquid storage device; pressure transmission liquid is filled in the lower part of the liquid storage device; the upper part of the liquid storage device is connected with a first pressure leading-in end of a pressure transmitter through an air pipe; the lower part of the liquid storage device is connected with a second pressure leading-in end of the pressure transmitter through a pressure transmission pipe; an electrical signal output end of the pressure transmitter is connected with a data acquisition and transmission system electrically; the data acquisition and transmission system is communicated with a control centre. The device has a simple structure and high precision, is convenient to operate, and can realize long-term automatic monitoring of high-speed railway structure settlement in areas with harsh environment.

Description

technical field [0001] The invention belongs to the field of surveying and mapping science and technology, in particular to a settlement monitoring device and a monitoring method for high-speed railway structures. Background technique [0002] my country's railways are developing by leaps and bounds. New high-speed passenger dedicated lines and reconstruction of existing railways are in the ascendant. High-speed driving requires the line structure to provide a track system with high ride comfort. How to accurately monitor the settlement and deformation of structures has become a key technical issue for high-speed railways. [0003] There are two main types of traditional settlement deformation monitoring methods: one is the conventional measurement method (geodetic method and photogrammetry method); the other is the physical sensor method. Conventional measurement methods have the advantages of high measurement accuracy and reliable data, but they also have disadvantages s...
