Remote intelligent detection method and facility for subgrade settlement

Abstract

In the invention, a subgrade settlement numerical model is established based on subgrade design parameters, construction filling record data and FLAC<3D> technology; subgrade settlement real-time monitoring data are acquired by using a single-point settlement meter to realize real-time continuous monitoring of the stability of subgrade settlement, the real-time monitoring data are transmitted to a user computer, the subgrade settlement numerical model carries out comparative analysis on an actually measured subgrade settlement deformation value and a subgrade settlement threshold obtained through numerical analysis and analyzes and evaluates the stability of the subgrade settlement, and results are displayed by using a 3D visualization safety pre-warning platform; all the pre-warning information are sent to the phones of management staff through a short message module connected with the computer in a manner of short messages, and all the monitoring data automatically generate database files in a computer terminal to complete remote intelligent detection and analysis of the subgrade settlement. With the invention, relevant construction personnel on a railway and a highway can take preventive measures in time based on detection data information so as to improve the quality of subgrade construction and reduce hidden construction dangers.

Description

technical field [0001] The invention belongs to the field of basic engineering related to railways and highway subgrades, and is used for early warning of subgrade settlement stability safety; in particular, it relates to a remote intelligent detection and analysis method for subgrade settlement, and the invention also relates to a remote intelligent detection facility for subgrade settlement. Background technique [0002] Subgrade construction settlement control of railways and highways is more important, especially in special parts such as road-bridge transition sections, where subgrade differential settlement frequently occurs. Conventional settlement monitoring is also one of the projects that are required to be completed simultaneously with the design requirements and construction. On-site data collection is time-consuming and laborious. Therefore, it is of great significance to carry out research on remote intelligent detection of subgrade settlement. [0003] There ar...

AI Technical Summary

Problems solved by technology

[0003] At home and abroad, there is still little research on remote intelligent detection of subgrade settlement. Up to now, there has been no literature report on remote intelligent detection of subgrade settlement that integrates a numerical model of subgrade settlement and a three-dimensional visual safety early warning platform.
