Have to out : 1 temperature constructional reinforcing not can place in heat area to mass concrete design . temperature constructional reinforcing of bottom of mass concrete need content that owing to temperature change produce bottom control stress smaller than anti - pull strength at the same . get minimum rate of reinforcing to content construct request 得出： 1在大体积混凝土结构的温度构造钢筋配置中，构造钢筋不宜放置于高温区；大体积混凝土的底部温度构造钢筋应满足温度变化产生的底部约束拉应力小于混凝土同龄期的抗拉强度的要求，从而求出抗拉要求的最小配筋率。
