Abstract

The invention provides a method and system for remote intelligent monitoring and three-dimensional digital early warning of deep foundation pit bottom surface upheavals. A construction region deep foundation pit deformation stability three-dimensional numerical model is built based on deep foundation pit rock and earth mass physical and mechanics parameters, deep foundation pit region hydrogeological and engineering geological conditions and an FLAC3D technology. A deep foundation pit bottom surface upheaval deformation three-dimensional visualized safety early warning platform is built based on a VTK business software system. Foundation pit bottom surface upheaval deformation real-time monitoring data are acquired through a hydrostatic balance level and transferred to a remote monitoring and data processing machine, initial groups of data are utilized to finish parameter modification of the deep foundation pit deformation stability three-dimensional numerical model, follow-up real-time data and model parameter threshold values are compared, and the deep foundation pit bottom surface upheaval deformation three-dimensional visualized safety early warning platform shows and perform grading safety early warning to alert-exceeding parameters. All of early warning information is sent to mobile phones of relevant persons, and accordingly the remote intelligent monitoring and the three-dimensional digital early warning of the deep foundation pit bottom surface upheavals are finished.

Description

technical field [0001] The invention belongs to the technical field of deep foundation pit construction engineering related to urban subway stations, high-rise building foundation excavation, etc., and is used for remote intelligent monitoring and three-dimensional digital early warning of uplift deformation at the bottom of deep foundation pits; The digital early warning method also involves remote intelligent monitoring of deep foundation pit bottom uplift and a three-dimensional digital early warning system. [0002] Background technique [0003] With the expansion of the construction scale of urban subways and super high-rise buildings, there are more and more deep foundation pit construction projects. In the process of deep foundation pit construction, foundation pit instability accidents occur frequently, and the stability of foundation pits has attracted more and more attention from people in the industry. Considering the principles of safety and economy, it is of ...
