| Abstract: | The paper introduces the temperature control measures and construction methods in the large pile cap high-performance concrete construction of the passenger special lines,and adopts some measures by optimizing the proportional ratio,pre-burying the cool water in the internal part of the large pile cap concrete to lower the temperature,and covering the concrete surface with the earthwork cloth for the insulation,so as to have the better effect of controlling the cracks. |
