斜拉桥索塔大体积混凝土强度变化规律试验研究

Experimental Research on the Strength Change Laws of Mass Concrete of Cable-Stayed Bridge Pylon

根据成熟度理论,通过对某斜拉桥索塔部位内部不同位置的混凝土成熟度进行实时监测,并应用与施工现场相同配合比的混凝土建立成熟度与强度关系,分析大体积混凝土内部每个测点的混凝土强度变化规律和不同部位的混凝土强度变化规律,为后续模板拆除及施工提供理论基础。

According to the theory of maturity, by real -time monitoring on the maturity of internal different parts concreteof a cable - stayed bridge pylon, utilizing the same mixproportion of concrete to establish the relations of maturity -strength, to analysis the strength change laws of each measuringpoint of mass concrete and different parts of mass concrete, providesthe theoretical basis for the follow - up formwork dismantlingand construction.
