大体积混凝土底板施工裂缝控制

The Control of Crack with the Bottom of Large-volume Concrete

大体积混凝土施工的一个特点是容易产生温度裂缝．在华南大厦3600m2混凝土底板施工中，通过优化配合比、温度收缩应力计算、加强测温控制等措施，防止了温度裂缝的产生．取得了较好的效果．

A characteristic of large volume conerete construction is producing erack easily. In the 3600m2concrete bottom's construction of 'South China Hotel', the thermal crack is avoided through the techoicalmeasures, such as optimiting the mixture ratio, calculating thermal stress, strengthening temperature control.
