浅谈大体积混凝土基础温度控制

Discussion on Temperature Control of Mass Concrete Foundation

文章以烟囱基础为例展开讨论,基础截面长宽尺寸为26.5m×16m,整个基础坐落在60根混凝土方桩之上,为钢筋混凝土结构基础,混凝土强度等级为C40,混凝土浇筑量约1500立方米,环壁外围为斜坡型,基础底板整体厚度2.5m,基础环壁为环形锥台,基底标高-5.100m,其中垫层厚度为0.1m,采用150mm厚的C20素混凝土,环壁顶高±0.500m。

Taking the chimney foundation as an example,the length and width of the foundation section is 26.5m × 16m,and the whole foundation is located on 60 concrete square piles,which is the foundation of reinforced concrete structure and the concrete strength grade is C40.the length and width of the foundation are 26.5m × 16m,and the whole foundation is located on 60 concrete square piles.The amount of concrete pouring is about 1500 cubic meters,the outer side of the ring wall is slope type,the overall thickness of foundation bottom plate is 2.5m,the ring wall of foundation is annular cone table,the elevation of foundation is-5.100m,in which the thickness of cushion is 0.1m,and C20 plain concrete with 150mm thickness is adopted.The top height of the ring wall is ±0.500m.
