Problems solved by technology

If there are pipelines, subsea tunnels, subways and other buildings / structures around the project, during the dynamic compaction construction, if the energy level of the dynamic compaction machine is selected conservatively, the compaction effect of the foundation cannot be guaranteed. If the energy level of the dynamic compaction machine is selected aggressively , there is no guarantee whether the stress generated during construction will affect or damage adjacent buildings / structures

Abstract

The invention discloses a model selection method for dynamic compaction mechanical equipment close to a subway or a tunnel, which comprises the following steps of: firstly, acquiring exploration data of a construction area and an adjacent area through geological exploration, establishing a three-dimensional geological model according to the exploration data, analyzing the pressure stress of an adjacent building/structure, and acquiring a calculated value of the pressure stress of the adjacent building/structure; and checking calculation is carried out according to the prepared dynamic compaction mechanical equipment and the established three-dimensional geological finite element analysis model, and finally the corresponding dynamic compaction mechanical equipment is obtained according to the checking calculation. And the influence or damage of stress damage generated during dynamic compaction on adjacent buildings/structures can be avoided.

Description

technical field [0001] The invention relates to a type selection method for dynamic tamping mechanical equipment near subways or tunnels, and belongs to the technical field of building construction. Background technique [0002] During the actual construction of dynamic compaction machinery, there are often no many buildings / structures around, but the environment of on-site construction is abrupt. If there are pipelines, subsea tunnels, subways and other buildings / structures around the project, during the dynamic compaction construction, if the energy level of the dynamic compaction machine is selected conservatively, the compaction effect of the foundation cannot be guaranteed. If the energy level of the dynamic compaction machine is selected aggressively , there is no guarantee whether the stress generated during construction will affect or damage adjacent buildings / structures. Contents of the invention [0003] The purpose of the present invention is to provide a metho...
