Sedimentation analyzing method based on pile foundation character analysis

Abstract

The invention relates to a sedimentation analyzing method based on pile foundation character analysis. A load transmission method and a shear displacement method are combined for conducting pile foundation character analysis, a load-displacement-time three-dimensional function graph is drawn, the quantitative relation among the load, the displacement and the time is established, and overload pre-pressing construction is instructed. According to the sedimentation analyzing method, the quantitative relation among the load, the displacement and the time can be provided, the solidification process of a new bridge part is accelerated through an overload pre-pressing method before a new bridge and an old bridge are connected, so that the later-period sedimentation deformation of the new bridge part is reduced, the additional stress of the structure is relieved, and normal use and the safety performance of the bridge are ensured.

Description

technical field [0001] The invention relates to the field of pile foundation settlement, and more specifically relates to a settlement analysis method based on pile foundation property analysis. Background technique [0002] At the end of the 20th century, the country experienced large-scale engineering construction. After more than 20 years of rapid development, the speed of new urban bridges tended to slow down, and the scale gradually shrank. With the rapid development of the economy, the problem that gradually emerged in the later stage of large-scale construction is that the original bridge will soon be unable to meet the traffic demand, resulting in traffic congestion and structural overload, reducing the service life and safety performance of urban bridges. Therefore, the existing bridge needs to be reconstructed and widened. [0003] In the process of bridge widening, after several years of operation after the completion of the old bridge, the settlement deformation...

With the rapid development of the economy, the problem that gradually emerged in the later stage of large-scale construction is that the original bridge will soon be unable to meet the traffic demand, resulting in traffic congestion and structural overload, reducing the service life and safety performance of urban bridges

According to the existing settlement analysis, only the relationship between the pile top load and the pile top settlement displacement can be obtained, and it is impossible to intuitively determine how to preload the new pile foundation
