摘　　要：文章结合厦门港海沧港区12#泊位液体化工码头工程实例,通过理论计算,研究在不同施工条件下,温度应力的数值和分布位置,从而科学指导确定施工中的底膜厚度和选择合适的配筋率;对于类似高桩墩式结构承台裂缝控制具有借鉴意义。By citing liquid chemical berth No.12 project of Haichang Harbour at Xia＇ men Port, theoretic calculation is adopted to research the temperature stress values and distribution location under different construction conditions, which leads to accurate thickness of soffit formwork and proper reinforcement ratio being applied in the construction. The above will provide references for the control of fissures in the platform supported on piles.

关 键 词：大体积混凝土 温度应力 底膜厚度
