基于绿色建造理念的钢筋混凝土地下室温度裂缝研究

Research on the Temperature Crack of Reinforced Concrete Basement Based on the Green Construction Concept

裂缝是住宅建筑工程中常见的质量问题。裂缝引起混凝土结构中钢筋锈蚀,影响结构的耐久性;裂缝损害建筑的美观,造成使用者的不安全感;贯通裂缝会产生渗漏水隐患,影响使用;裂缝导致结构刚度的减小,影响结构安全。据不完全统计,地下室裂缝产生的原因,80%以上是温度变化和混凝土收缩。本文结合绿色建造理念以温度裂缝防治为主要研究目标,对各种规模的地下室温度应力做分析,再紧跟数字化时代步伐,使用计算软件进行数值分析,找到温度应力的分布规律,研究结果用以指导钢筋混凝土地下室的设计及施工管控。同时,研究结论,也验证绿色建造理念在地下室结构工程的应用先进性。这一课题对于减少裂缝、缩小裂缝宽度,提高地下室品质有着深远的意义。

Cracks are a common quality problem in residential construction projects.Cracks cause corrosion of steel bars in concrete structures.affecting the durability of the structure:Cracks damage the aesthetics of buildings and create a sense of insecurity for users:Penetrating cracks can create hidden dangers of water leakage and affect use:Cracks lead to a decrease in structural stiffness and affect structural safety.According to incomplete statistics,over 80%of the causes of basement cracks are temperature changes and concrete shrinkage.This article combines the concept of green construction with the main research goal of temperature crack prevention and control.It analyzes the temperature stress of various sizes of basements,and then follows the pace of the digital era by using numerical analysis software to find the distribution pattern of temperature stress.The research results are used to guide the design and construction control of reinforced concrete basements.At the same time.the research conclusion also verifies the progressiveness of the application of the green construction concept in the basement structural engineering.This topic has profound significance in reducing cracks,reducing crack width,and improving basement engineering quality.
