Deformation monitoring method for deep foundation pit under soft soil area supporting system

Abstract

The invention relates to a deformation monitoring method for a deep foundation pit under a soft soil area supporting system. The method specifically comprises the steps that foundation pit deformationdata are transmitted to a central control computer through a foundation pit deformation detection device; the central control computer receives the foundation pit deformation data in real time and compares the received foundation pit deformation data with a set value in real time, and if the received foundation pit deformation data exceeds the set value, alarm information is sent out; the centralcontrol computer establishes a cloud database for the received foundation pit deformation data, and establishes a risk assessment system for checking at any time according to the monitoring data; andthe central control computer establishes a BIM entity model according to the shape and the deformation condition of the foundation pit, and monitors the deformation condition of the foundation pit through the BIM entity model. Relatively continuous real-time monitoring on deformation of the side wall of the foundation pit can be achieved, besides, local and overall deformation conditions of the foundation pit can be accurately reflected, a reasonable risk assessment system is established, the effects of reference and guidance are achieved, and the BIM model reflects the overall deformation condition more visually.

Description

technical field [0001] The invention relates to the technical field of foundation pit deformation monitoring, in particular to a deformation monitoring method for deep foundation pits under a support system in soft soil areas. Background technique [0002] Whether it is modern high-rise, super high-rise buildings or urban subway stations, the excavation of deep foundation pits is involved. These structures are generally located in the center of the city. According to the degree of dense buildings and complex and changeable surrounding environments, different foundation pits are used method and the corresponding support system make foundation pit deformation monitoring indispensable in the foundation pit construction process of the above-mentioned structures. Foundation pit monitoring technology has become an important guarantee method for construction. How to effectively and quickly carry out foundation pit safety monitoring has become a A difficult and key point in building...

Problems solved by technology

[0003] At present, most foundation pit deformation monitoring uses instruments such as total stations, levels, and inclinometers, which require manual timing measurements and readings, which not only increases labor intensity, but also makes it difficult to achieve relatively continuous real-time monitoring of the deformation of the side walls of the foundation pit. Accurately reflect the partial and overall deformation of the foundation pit. It cannot monitor the dangerous parts of the foundation pit in real time, find the source of danger in time and give a timely warning, and cannot play a good role in risk assessment and operation guidance.
