【摘要】 通过对大型连续地下室结构各阶段混凝土收缩状态以及地基与桩水平阻力约束作用的分析,建立了计算结构收缩应力的计算模型,并提出将收缩应力作为结构初始应力,进行预应力正常使用极限状态设计的设计方法。更多还原

【Abstract】 By analyzing the status of the concrete shrinkage in different stages and constraints effects of the basement,a calculating model of the structure shrinkage stress is introduced in this paper,and a prestressed concrete design method with the consideration of concrete shrinkage is put forward.更多还原
