Abstract

The invention provides an oil and gas pipe suspension cable crossing simulation analysis method. The method comprises the following steps that an oil and gas pipe suspension cable crossing simulationanalysis model is built; for different stages of the actual construction process, load working condition analysis is carried out, an external load is applied to the oil and gas pipe suspension cable crossing simulation analysis model by utilizing an analysis result, and simulation calculation of each construction stage of the suspension cable crossing structure is carried out; each influence factor in the construction process of the suspension cable spanning structure is comprehensively considered, static analysis and / or modal analysis and / or dynamic analysis is carried out on the analogue simulation calculation result of each construction stage of the suspension cable spanning structure, and displacement change and stress change of each component of the suspension cable spanning structureis obtained; and the simulation calculation result forms a dynamic tower stabilizing load calculation technology so as to guide all components to be dynamically adjusted in the construction process of the suspension cable spanning structure, and a construction scheme is generated. The nonlinear behavior of the suspension cable spanning structure in actual construction can be analyzed, and reference is provided for construction design of the suspension cable spanning structure.

Description

technical field [0001] The invention relates to an analysis method for a large-scale spanning simulation model of an oil and gas pipeline, in particular to a simulation analysis method for an oil and gas pipeline suspension cable spanning. Background technique [0002] Generally speaking, oil and gas pipeline spanning is an engineering structure that uses a bridge-like structure to carry oil and gas pipelines through canyons, rivers and other regions. Generally, oil and gas pipeline spanning has main structural forms such as suspension cable, cable-stayed cable, and truss, among which suspension cable and cable-stayed cable are the most widely used spanning structures of oil and gas pipelines at home and abroad. These two structures are mainly composed of substructure (foundation and anchorage structure), tower, cable system, bridge deck structure and so on. [0003] The inventors have found through research that the suspension cable spanning structure of the oil and gas pi...
