Approximate calculation method and system for maximum deformation capacity of support structure

Abstract

The invention provides an approximate calculation method and a system for maximum deformation capacity of a support structure. According to the system and the method, a maximum displacement value delta 1 of multiple curve equations y = g (x) and a corresponding displacement value delta 2 of the linear deformation equation y = k x are superposed, and the superposition result of the delta 1 and thedelta 2 is used as the final displacement of the support structure under the bearing capacity limit state, and can be used for approximately calculating the maximum deformation capacity of the supportstructure under the bearing capacity limit state. According to the approximate calculation method and the system for the maximum deformation capacity of the support structure, the potential safety hazard brought by the problems of incomplete deformation monitoring technology, incorrect data analysis and the like can be eliminated, and measures can be taken in advance according to calculation analysis results to reduce adverse effects caused by deformation of a foundation pit as much as possible.

Description

technical field [0001] The invention relates to an approximate calculation method and system for the maximum deformation capacity of a support structure. Background technique [0002] With the rapid development of my country's economy, a large number of buildings are built, and there are more and more foundation pit projects. The excavation process of foundation pits often causes internal force and deformation of the support structure and deformation of the soil. Unexpected changes cause serious engineering accidents. Affect the safety of the entire project and the environment. The deformation of the support structure is an intuitive reflection of the interaction between the support structure and the soil during the excavation of the foundation pit, and it is also an early warning of various emergencies. Therefore, it is necessary to propose a relatively complete calculation system to calculate and analyze the deformation and displacement of the foundation pit, and take meas...
