【摘要】：混凝土結(jié)構(gòu)長期暴露在氣象環(huán)境中,受各種氣象因素的影響。濕度影響混凝土結(jié)構(gòu)的耐久性和材料的干燥收縮,目前基于原始濕度數(shù)據(jù)的研究極少。該文以廣州地區(qū)為例,闡述了一種由30年原始?xì)庀髷?shù)據(jù)得到逐時(shí)氣象數(shù)據(jù)的快速高效插值方法,引入平穩(wěn)二項(xiàng)隨機(jī)過程模型。對(duì)逐時(shí)濕度氣象數(shù)據(jù)進(jìn)行概率統(tǒng)計(jì),提出并求出50年一遇混凝土結(jié)構(gòu)用標(biāo)準(zhǔn)日濕度作用模型,進(jìn)而得到標(biāo)準(zhǔn)年濕度作用模型。濕度作用模型反映濕度日(年)變化規(guī)律,并為有關(guān)日(年)濕度作用分析提供連續(xù)數(shù)值模擬參數(shù),供有關(guān)濕度對(duì)結(jié)構(gòu)耐久性和干燥收縮影響分析參考。
[Abstract]:Concrete structure is exposed to meteorological environment for a long time and affected by various meteorological factors. Humidity affects the durability of concrete structure and the drying shrinkage of material. At present, there is very little research based on the original humidity data. This paper, taking Guangzhou as an example, describes a fast and efficient interpolation method to get hourly meteorological data from 30 years original meteorological data. This paper introduces the stationary binomial stochastic process model, carries on the probability statistics to the hourly humidity meteorological data, puts forward and obtains the standard daily humidity action model for the concrete structure once in 50 years. Then the standard annual humidity action model is obtained. The humidity action model reflects the daily (annual) variation of humidity and provides the continuous numerical simulation parameters for the analysis of the daily (annual) humidity. It provides a reference for the analysis of the effect of humidity on the durability and drying shrinkage of the structure.

【正文快照】： 環(huán)境濕度對(duì)混凝土的碳化速度和鋼筋銹蝕有很大影響,混凝土結(jié)構(gòu)材料的干燥收縮變形,引起結(jié)構(gòu)開裂,所以,濕度對(duì)混凝土結(jié)構(gòu)耐久性影響很大,有必要對(duì)濕度作用進(jìn)行深入研究。為減輕濕度作用對(duì)混凝土結(jié)構(gòu)的危害,提高結(jié)構(gòu)安全性、適用性、耐久性,研究分析濕度作用變化規(guī)律、建立標(biāo)準(zhǔn)，
