| Abstract: | Based on numerical emulation computation for concrete cable tower of a large-span cable-stayed bridge under effect of temperature and shrinkage in combination with analysis for measured data on site,this paper searches after the cracking mechanism of bridge tower concrete under deformed load during construction and proposes structure treatment and construction measures for control of structural cracks of similar concrete. |
