【摘要】：目前,國內(nèi)的學(xué)者對懸索橋溫度場及其效應(yīng)研究都非常重視。橋梁結(jié)構(gòu)溫度場及其效應(yīng)的研究在最近幾十年得到了快速發(fā)展,但由于主纜中的溫度場分布和變化異常的復(fù)雜和不確定,使得溫度效應(yīng)對懸索橋施工、懸索橋受力和懸索橋安全性的影響程度很難被精確得確定。 本文主要以魚嘴長江大橋項(xiàng)目為背景依托工程,對不同季節(jié)、不同施工階段的山區(qū)大跨徑懸索橋主纜溫度場進(jìn)行了深入的研究。為此,本文進(jìn)行了如下幾方面的工作： 1)對懸索橋主纜溫度場影響因素與溫度效應(yīng)對于結(jié)構(gòu)的影響以及國內(nèi)外研究現(xiàn)狀進(jìn)行了簡要概述； 2)對熱物性參數(shù)實(shí)驗(yàn)測試的理論進(jìn)行了闡釋,并對主纜模型熱物性參數(shù)進(jìn)行了研究分析； 3)依靠有限元分析理論,以及有限元軟件Midas/Civil軟件對背景工程中主纜的溫度效應(yīng)進(jìn)行詳細(xì)仿真分析計(jì)算； 4)通過分析主纜的溫度效應(yīng),提出了在不同施工階段溫度效應(yīng)對于結(jié)構(gòu)的影響程度,對山區(qū)復(fù)雜環(huán)境下大跨度懸索橋的架設(shè)施工和后期運(yùn)營維護(hù)具有重要的指導(dǎo)意義和參考價(jià)值。
[Abstract]:At present, domestic scholars attach great importance to the study of temperature field and its effects of suspension bridge. The study of temperature field and its effect of bridge structure has been developed rapidly in recent decades. However, due to the complexity and uncertainty of temperature field distribution and variation in the main cable, the temperature effect is used in the construction of suspension bridge. The influence of suspension bridge force and suspension bridge safety is difficult to be accurately determined. Based on the Yuzui Yangtze River Bridge project, the temperature field of the main cable of the mountain long span suspension bridge in different seasons and different construction stages is studied in this paper. Therefore, this paper has carried on the following aspects of work: 1) the influence factors of the temperature field and the temperature effect of the main cable of suspension bridge on the structure and the research status at home and abroad are briefly summarized; 2) the theory of experimental test of thermal physical parameters is explained, and the thermal physical parameters of the main cable model are studied and analyzed. 3) based on the finite element analysis theory, The temperature effect of the main cable in the background engineering is analyzed by the finite element software Midas / Civil in detail. 4) by analyzing the temperature effect of the main cable, the influence degree of the temperature effect on the structure in different construction stage is put forward. It has important guiding significance and reference value for erection construction and later operation and maintenance of long-span suspension bridge in complex environment in mountainous area.
