Analysis on the Design Optimization of the Prestressed Cap Beam of the Portal Frame of the Suburban Expressway Based on the Control of Construction Period
The construction environment of suburban expressways is complex,with many uncertain factors.Under the superposition of multiple factors,there may be a lag in the construction schedule.In order to ensure the smooth opening of the construction project,it is necessary to reasonably compress the construction period of each construction link.As one of the widely used structural forms in the interchange areas of suburban expressways,the construction period of the prestressed cap beam of the portal frame has an important impact on the progress of the whole project.Based on the prestressed cap beam of the portal frame of a two-way eight-lane expressway under construction,the optimal design scheme under the compression of construction period is analyzed.
