Abstract

The invention discloses a deep foundation pit dynamic construction real-time monitoring and early warning system and a use method. The system comprise a pre-processing end, a cloud processing platformand a post-processing end, the pre-processing end, the cloud processing platform and the post-processing end are connected in sequence, the pre-processing end is used for collecting foundation pit dynamic construction data and achieving information interaction through 5G transmission, the cloud processing platform integrates a pre-processing end sensor module and a three-dimensional information acquisition module to upload data, constructs a DEM comprehensive terrain grid, imports stratum information, carries out foundation pit excavation through a built-in rock-soil simulation module, and realizes slope and foundation pit instability simulation prediction. A four-dimensional live-action chromatic aberration graph with a time sequence is generated in combination with a BIM foundation pitthree-dimensional model, a rock-soil simulation three-dimensional model and feature point data, and finally, the four-dimensional live-action chromatic aberration graph is displayed on a mobile phoneand a computer through a post-processing end, so that visualization and collaboration of construction information are realized.

Description

technical field [0001] The invention belongs to the technical field of monitoring and early warning systems for deep foundation pit construction, and in particular relates to a real-time monitoring and early warning system for dynamic construction of deep foundation pits and a use method thereof. Background technique [0002] Excavation methods for deep foundation pits include slope excavation, central island excavation, basin excavation and reverse excavation. The site environment of foundation pit excavation is usually relatively complex, and various risk factors are hidden in the geological conditions and surrounding environment, which cannot be accurately predicted in the construction design, and will appear as the construction excavation progresses. The excavation of the foundation pit is a process of continuous unloading of the excavation surface and the surrounding soil. The soil has rheological properties. When the soil is continuously unloaded, this characteristic w...
