[0003] At home and abroad, there is still little research on remote intelligent 3D digital early warning of subgrade surface settlement. Up to now, there have been no literature reports on remote intelligent 3D digital early warning of subgrade surface settlement that integrates a numerical model of subgrade settlement and a 3D visual safety early warning platform.

According to the invention,a subgrade surface settlement value model is established according to subgrage design parameters and construction filling record data by using the FLAC three-dimensional technology; and is based on a three-dimensional visualized safety early warning platform established by a VTK business software system; the invention is characterized in that a real time monitoring data of subgrade surface settlement is collected through a hydrostatic level arranged on the subgrade, and the real time monitoring data is transmitted to an user remote computer, the actual measured deformation value of the subgrade surface settlement obtained by the subgrade settlement value model is compared with the subgrade settlement threshold value and then an analysis is carried out, the graded prealarming is carried out on the stability of the subgrade surface settlement, and is displayed through the three-dimensional visualized safety early warning platform, and all the early warning information is send to a cellphone of relative management staff by a short message mode through a short message module connected to the computer, and the remote intelligent three-dimensional digital early warning for the subgrade surface settlement can be completed. The prevention measurements can be timely adopted according to the early warning information by the relative management staff in the railway and road departments; and the driving and traffic security can be enhanced.
Description
technical field [0001] The invention belongs to the field of foundation engineering such as railways and highway subgrades, and is used for early warning of roadbed surface settlement stability safety; in particular, it relates to a remote intelligent three-dimensional digital early warning method for subgrade surface settlement, and the invention also relates to a remote intelligent three-dimensional digital early warning method for subgrade surface settlement system. Background technique [0002] The road subgrade surface of railways and highways, especially the transitional sections of roads and bridges, etc., is always a difficult problem to control road settlement during and after the construction is completed. After the project was put into use, subgrade surface subsidence often occurred, which brought many hidden dangers to railway traffic safety and road traffic safety. Therefore, it is of great safety significance to develop remote intelligent three-dimensional dig...
