Space analysis of Block 0 of prestressed concrete continuous rigid bridge

continuous rigid bridges;  Block 0;  Space;  Stress analysis

Taking the main bridge of Shuinan Bridge as the research object, the large-scale general finite element program MIDAS/Civil was used to establish the spatial finite element calculation model of Block 0 of the pier, and the stress of Block 0 under the construction stage and the operation stage of the bridge was analyzed. The calculation results show that except for the slight weakness of the diaphragm manhole part, the rest of the pier No. 0 block meets the specification requirements, and the calculation results have provided a basis for the design of the bridge, and also have certain reference value for the design of block 0 of similar bridges.
