Abstract

An embodiment of the present application provides a method for adjusting the piers and abutments of a bridge in a karst area, including adjusting and mapping the geological conditions of the preset area of ​​the bridge, and delineating the optimization range of the abutments; according to the karst development area within the optimization range, The plane position of the karst weakly developed area and the karst undeveloped area is determined to determine the position of the bridge in the horizontal direction; according to the karst development in the longitudinal direction of the bridge, the set position of the abutment and the hole of the abutment are determined across.

Description

technical field [0001] The present application relates to the technical field of bridge construction in karst areas, in particular to a method for adjusting piers and abutments of bridges in karst areas. Background technique [0002] When the bridge passes through the karst area, the piers of the bridge often encounter karst caves in the shape of beaded and lenticular. It is bound to affect the construction, safety and economic cost of the bridge. Contents of the invention [0003] In view of this, the embodiment of the present application expects to provide a method for adjusting the abutment of a bridge in a karst area, so as to facilitate setting the abutment of a bridge when the bridge crosses the karst area. In order to achieve the above beneficial effects, the technical solutions of the embodiments of the present application are implemented as follows: [0004] The embodiment of the present application provides a method for adjusting the piers and abutments of brid...
