Abstract

The present invention relates to the field of bridge construction, in particular to a preloading method for a curved surface support, comprising: selecting a number of target support columns from the support columns of the curved surface support, selecting monitoring points from the upper and lower ends of the target support column, and obtaining the preloading method of the curved surface support The monitoring data of each monitoring point before pressing; Wherein, the support column is a structure used to support the supported object in the curved surface support; the curved surface formed on the top of the curved surface support is evenly covered with the first preloaded material; according to The load of the supported object on the curved surface support, the second preloaded object is added to the first preloaded object corresponding to the load on the curved surface support greater than the average load of the curved surface support according to the preset rules; The monitoring data of the monitoring points, when the monitoring data of each preloading period meet the preset requirements, the preloading test of the curved surface support ends. The invention realizes fast and accurate acquisition of monitoring data of the curved surface support, so as to ensure the accuracy of the preloading result.

Description

【Technical field】 [0001] The invention relates to the field of bridge construction, in particular to a preloading method for a curved support. 【Background technique】 [0002] With the rapid development of my country's infrastructure construction, a large number of cast-in-place bridges need to be erected. In bridge construction, it is necessary to preload the support with heavy objects in advance to ensure the reliability of the support and understand the elastic deformation of the support during construction. , and eliminate the inelastic deformation of the bracket, and test the bearing capacity and stability of the structure. Therefore, the preloading of the bracket is an indispensable construction process after the bracket is erected. [0003] Compared with the planar support, the force of the existing curved support is more complicated than that of the planar support, and the preloading of the curved support cannot be carried out in the way of preloading the planar suppo...
