The Influence Of Structure Performance In The Construction On Arch Cantilever And Construction Control

The construction on arch cantilever method because of its mature technology, strong ability to adapt to the complex terrain, is widely applied in southwest China. Taking guizhou ancestral temple edge aqueduct as the research object, on cantilever arch cast-in-situ arch bridge construction control of several key problems of related research, mainly has the following several aspects:①According to the cantilever arch cast-in-situ construction features of arch bridge, expounds the construction process of the cable force calculation and arch ring points ring poured subsection program optimization method, key steps of construction control calculation, including the guy at the beginning of the cable force of a value and change, the arch ring poured subsection procedure is optimized, the reasonable arch ring pouring process.②With the use of bailey arch bridge as the background, the arch ring- arch combination problem studied, found by calculation, concrete arch ring undertake accounted for about 48% of the total weight.③With the use of bailey arch bridge as the background, and analyses the influence of different flat vertical union arrangement berea influence the stability of the arch; Local strengthen upper chord, foot arch arch and vault of bracing to decorate, can better increase the stability of arch; The different methods of arch foot constraint has a great influence on the stability of the arch, arch the stability of the arch foot consolidation is bigger than the stability of the hinged arch arch foot a lot④The main construction procedure by ancestral temple edge aqueduct in the construction monitoring results with the theoretical value of contrast, showed that the arch in the construction process of the linear small deviation, uniform stress distribution, structure of security and stability. Show that monitoring methods used in this paper, the ancestral temple edge aqueduct is reasonable and effective.
