摘要
运用有限元法,对新沭河泄洪闸之海漫温度应力及干燥收缩应力进行计算分析.计算结果表明,对于厚度较薄的大面积混凝土,干燥收缩和温度作用导致混凝土开裂,采用聚丙稀纤维混凝土,能够取得较好的预防温度、干燥收缩裂缝的效果.
In this paper, the stress of temperature and drying shrinkage of riprap is calculated by FEM in the Xinshu River flood diversion sluice engineering. By the calculation result, drying shrinkage and temperature effect cause concrete crack. Polypropylene fiber concrete may take the effect to prevent the crack caused by temperature and drying shrinkage.
