摘　　要：在大跨度混凝土水平结构的施工过程中,某层混凝土的浇筑过程、上层混凝土的浇筑过程以及该层模板支撑体系的拆除过程,是影响挠度变化的关键。为了精确的对混凝土水平构件的挠度变化进行测量,并保证其在整个施工过程中测量的精度,提出了预埋构件的测量方法。During construction process of large span horizontal concrete structure, the casting process of this layer of concrete ,the casting process of upper layer of concrete and demolition process of this layer of support system of this layer formwork are the key factors influencing the deflection. In order to accurately measure the deflection var- iation of the horizontal concrete members and ensure the measurement accuracy during the whole construction process ,the measurement method of pre-embedded structures members were put forward.
