Embodiment Construction
[0077] The method for automatically optimizing the axial force data of the large-scale foundation pit support body provided by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer with reference to the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.
[0078] Through the introduction of the background technology, we know that the comprehensive axial force data measured by the steel bar meter is equivalent to the entire section of the support body of the foundation pit directly based on the coordination conditions of steel bar and concrete deformation, and the calculated axial force of the support body of the foundation pit ca...

The invention discloses an automatic axial force data optimization method of a large foundation pit supporting body and belongs to the field of foundation pit engineering. The large foundation pit supporting body is a steel bar concrete beam, a supporting body model with the same cross section, same reinforcing bars and same concrete proportion as the foundation pit supporting body and cast simultaneously is arranged in a construction site, a foundation pit supporting body internal force exerted to a first steel bar meter is automatically removed by arranging the first steel bar meter and a second steel bar meter and utilizing an intelligent monitoring platform, accordingly a loaded axial force in the internal force is effectively stripped, then the loaded axial force data measured by the steel bar meters are equivalent to the calculated loaded axial force, on the cross section of the whole foundation pit supporting body, of the foundation pit supporting body according to the deformation compatibility conditions of steel bars and concrete. The loaded axial force calculated by utilizing the method conforms to the actual effect of a project and the axial force of the foundation pit supporting body, can well serve for foundation pit construction and has the important significance on monitoring and foundation pit safety insurance.
Description
technical field [0001] The invention relates to an automatic optimization method for axial force data of a large foundation pit support body, belonging to the field of foundation pit engineering. Background technique [0002] In large-scale foundation pit engineering, foundation pit support structure is very important. Reinforced concrete support structure is the more common foundation pit support structure. Support deformation and support axial force are important basis for evaluating the safety of the support structure and the entire foundation pit project. [0003] At present, the axial force on the reinforced concrete support structure is mainly measured by embedding a vibrating wire stress gauge in the support structure. The calculation method of the axial force of the reinforced concrete support structure is as follows: the reinforcement meter is connected in series to the main reinforcement of the support structure, and the axial force on a certain steel bar is conv...
