Safety monitoring system for horizontal displacement of foundation pit slope

Abstract

The invention provides a safety monitoring system for horizontal displacement of a foundation pit slope. The safety monitoring system comprises a horizontal displacement detection system, a monitoring information processing system and a visual management system, the horizontal displacement detection system comprises a data acquisition unit and a parameter setting unit, the data acquisition unit is used for acquiring initial reading of a monitoring point and data information of each displacement change, and the parameter setting unit is used for setting acquisition parameters and an early warning judgment mode according to a user instruction; the monitoring information processing system is used for analyzing the monitoring information and outputting early warning judgment information based on an analysis result; the visual management system is connected with the monitoring information processing system, and the visual management system is used for carrying out visual display and displacement factor analysis on the monitoring data, so that manual detection errors can be effectively avoided, the detection precision and efficiency are improved, meanwhile, abnormal alarm is carried out in time, and the change influence factors of the horizontal displacement are automatically analyzed.

Description

technical field [0001] The invention relates to the technical field of building measurement, in particular to a safety monitoring system for the horizontal displacement of foundation pit slopes. Background technique [0002] With the acceleration of the urbanization process, the demand for adding high-rise buildings such as subways and residential buildings and office buildings has increased. Many high-rise buildings or large commercial areas usually have to excavate deep foundation pits to increase the underground space of the plot. Deep foundation pits If the horizontal displacement exceeds the allowable deformation range, it will affect the surrounding buildings or cause huge asset losses. How to obtain the displacement of the enclosure structure and the deformation of the soil in a timely manner, and ensure the safety of the foundation pit during the construction period, requires the foundation The pit is used to measure the deep horizontal displacement. However, at pre...

Problems solved by technology

However, at present, the monitoring and early warning of the foundation pit is mainly determined by the accumulated displacement and displacement change rate value detected manually or by instruments. There may be data errors in the data entry process, or the alarm value monitoring is not accurate enough due to the complex terrain. In addition, it is impossible to automatically analyze the main influencing factors of the displacement of the foundation pit in order to prevent it in time
