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 optimization method for axial force data of a large-scale foundation pit support body, which belongs to the field of foundation pit engineering. The support body of the foundation pit is a reinforced concrete beam, and a support body model with the same cross section, the same reinforcement, the same concrete ratio as the foundation pit support body is set at the construction site, and the support body model is poured at the same time. The second steel bar meter uses the intelligent monitoring platform to automatically remove the internal force of the foundation pit support that the first steel bar meter is subjected to, thereby effectively stripping out the load axial force, and then measures the steel bar meter according to the coordination conditions of steel bar and concrete deformation. The load axial force data is equivalent to the entire foundation pit support body section, and the calculated load axial force of the foundation pit support body. The load axial force calculated by the method provided by the invention is more in line with the actual engineering effect and the axial force of the support body of the foundation pit, can better serve the foundation pit construction, and is of great significance for monitoring and ensuring the safety of the foundation pit.
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...
