Design device for foundation pit support framework scheme

Abstract

The invention provides a design device for a foundation pit enclosure framework scheme, which is used for designing the foundation pit enclosure framework scheme and is characterized by comprising an input display part, a profile data generation part, a to-be-screened scheme generation part, a safety coefficient calculation part and a design scheme determination part, the input display unit displays a cross-section designation screen and displays a stored foundation pit model diagram so that a user designates a cross-section corresponding to the enclosure framework, and the cross-section data generation unit generates cross-section data for enclosure framework calculation corresponding to the cross-section. The input display part is used for displaying a design parameter input picture, so that a user inputs a plurality of enclosure framework design parameter ranges as a plurality of to-be-screened schemes, and the safety coefficient calculation part is used for calculating enclosure framework safety coefficients corresponding to the to-be-screened schemes respectively; and the design scheme determination part determines the to-be-screened scheme of which the safety coefficient of the enclosure framework accords with a preset safety threshold interval from the plurality of to-be-screened schemes and takes the to-be-screened scheme as an enclosure framework design scheme.

Description

technical field [0001] The invention belongs to the field of urban construction, and in particular relates to a design device for a foundation pit enclosure protection framework scheme. Background technique [0002] Due to the high uncertainty of the physical and mechanical properties of rock and soil materials, foundation pit engineering has high risks, especially deep foundation pit engineering. Therefore, in order to ensure the stability of the foundation pit, it is usually necessary to set up corresponding foundation pit enclosures in the foundation pit so that the displacement of the soil at the bottom of the pit and outside the pit can be controlled within a certain range, ensuring the stability of the foundation pit and the safety of operations in the pit . [0003] When designing the foundation pit enclosure, it is necessary to consider the stiffness and strength of the entire support system according to the soil layer system around the foundation pit, while the tra...

Problems solved by technology

However, since the foundation pit is often a temporary project, and the modeling of the foundation pit needs to rely on accurate geological data and structural data in the foundation pit, and there are various forms of enclosure structures, designers need to choose according to the depth of the foundation pit and environmental conditions. Different enclosures, therefore, the modeling of foundation pit engineering is also more complicated, and the entire modeling process is time-consuming and labor-intensive

[0005] Furthermore, designers often need to start modeling from scratch for each design scheme of foundation pit enclosure, and after building the calculation model, it still takes a lot of manpower to set the parameters of the model and post-process the calculation results. The analysis process after the modeling is also very time-consuming and labor-intensive
