Method and system for local translation correction of large chassis structure

Abstract

The invention provides a method and system for rectifying partial translation of a large chassis structure. The position where the displacement deviation of the large chassis structure engineering is detected is defined as a pre-cut structure; the structural main bodies on both sides of the local translation pre-cut structure of the large chassis structure are supported; through limited The element software simulates and calculates, and strengthens the main body of the structure; introduces the historical monitoring data of the site as the initial condition into the finite element calculation software, and arranges new dynamic monitoring measuring points for the main body of the structure; performs stress release on the soil on the other side of the translation , to form an operable space for underground horizontal pushback; cut off the connection between the pre-cut structure and the main body of the structure on the vertical plane, and become a free and independent rigid body that can be pushed; install horizontal graded loading on the translation side of the free independent rigid body The device applies an external force to move a free and independent rigid body; after the movement is completed and reaches a stable state, the structural main body of the cut structure is repaired. After the repair is completed, the soil is backfilled and the deviation correction is completed.

Description

technical field

[0001] The invention relates to the technical field of building construction, in particular to a building deviation correction method and system. Background technique

[0002] In the construction of construction projects, it often occurs that due to the construction line error, or the local displacement deviation of one or several buildings in the large chassis buildings during the construction of surrounding houses, the change of the structural stress system affects the structural bearing capacity. At present, The object of translation of the building is the overall translation, the structural system is relatively simple and single, and the force system hardly changes. To perform the overall translation, a large amount of labor is required to act on the jack at the same time, and the labor cost is very large, and there is a slight Inadvertently, an irreversible situation may even occur, resulting in safety accidents; for example, the patent document CN110185...
