Abstract

The invention discloses a foundation pit deformation real-time monitoring method and system, and relates to the technical field of foundation pit monitoring, and the method comprises the following steps: obtaining the field surveying and mapping data of a foundation pit; constructing a three-dimensional model of the foundation pit by utilizing a BIM system and based on field surveying and mapping data; setting a plurality of reference points in each plane of the foundation pit; generating a model reference point at a corresponding position in the three-dimensional model based on the positions of the reference points; on the basis of a preset foundation pit construction plan, performing construction simulation on the three-dimensional model through the BIM system, and obtaining simulation change tracks of all model reference points; obtaining actual change tracks of all reference points in the foundation pit, and constructing the foundation pit according to the foundation pit construction plan; and monitoring the deformation condition of the foundation pit in combination with the actual change track and the simulated change track, and if the deformation condition occurs, sending warning information to responsible personnel of the foundation pit. The method and the system have the effect of monitoring foundation pit deformation at any time.

Description

technical field [0001] The present application relates to the technical field of foundation pit monitoring, in particular to a method and system for real-time monitoring of foundation pit deformation. Background technique [0002] In order to ensure the safety and stability of the underground space formed by the excavation of the ground during the construction of the underground structure, the retaining structure, groundwater control, environmental protection and other measures are called foundation pit engineering. [0003] In the foundation pit engineering, if the foundation pit deformation occurs, the deformation of the foundation pit is often the prelude to the trend disaster behavior. Therefore, in order to ensure the safety of the foundation pit construction process, the monitoring of the foundation pit deformation is particularly important. Most of the deformation of the foundation pit is due to the excavation and unloading in the pit, which causes the displacement of...
