Field study of an integral backwall bridge
WebCurrent integral designs are often conservative and based on empirical values. This study is an analysis of an integral backwall bridge which was instrumented during construction and monitored for 2.5 years. Field instrumentation included strain gages, temperature probes and earth pressure cells. Webwingwalls. The horizontal bridge seat joint is shown in Figure 1. The vertical wingwall joints are similar except that only fillers and sealers are provided for unskewed bridges. …
