Description

Technical Field

[0001] The present invention relates to the technical field of construction digitization, and particularly to a digital interpretation method for complex working conditions based on construction time-varying characteristics. Background Art

[0002] The construction time-varying characteristics refer to the fact that during the construction process, the performance and state of the structure or system will change over time. Such changes are mainly reflected in the following aspects: change in structural force: during the construction process, the structural force state will change continuously with the construction progress. For example, in building construction, the building needs to undergo continuous changes in boundary conditions, load conditions, material properties, quality, stiffness, and structural systems, and finally complete the closure through system conversion; change in material properties: the material properties during construction will change over time. For example, the strength and elastic modulus of concrete will change over time, and the shrinkage and creep of concrete are also closely related to the loading age; foundation deformation: during the construction process, the foundation will continuously settle, and this settlement will generate secondary internal forces on the structure, affecting the linear control and installation accuracy of the structure.

[0003] When interpreting traditional construction time-varying characteristics, a large amount of manpower and material resources need to be invested, and the construction period is long. Especially in large-scale construction projects, it is very time-consuming, reducing work efficiency; traditional building construction focuses on technical management, resulting in omissions in the management system, prone to safety and quality problems, and the construction site management is complex, involving multiple links such as personnel, machinery, and materials, increasing the management difficulty.
