【摘要】:隨著我國交通事業(yè)的穩(wěn)步發(fā)展,橋梁的數(shù)量也與日俱增,然而我國現(xiàn)階段的橋梁使用年限較長,再加上其設計標準較低,所以橋梁破壞情況較為嚴重。因而對橋梁進行實時的養(yǎng)護顯得尤為重要。養(yǎng)護在保證橋梁使用性能,延長使用壽命方面有著極其重要的作用。 本文主要研究的是武漢三環(huán)線上五座橋梁的養(yǎng)護管理問題,這幾座橋梁都為鋼筋混凝土橋梁。而對于鋼筋混凝土橋梁來說,由于鋼筋混凝土材料的物理力學特性,會使得橋梁在使用過程中出現(xiàn)一些不可避免的問題,這些問題都使得橋梁需要進行預防性養(yǎng)護工作;由于鋼筋混凝土橋梁的結(jié)構(gòu)和類型趨于多樣化,也會造成橋梁因部分結(jié)構(gòu)出現(xiàn)損壞,而需要采用一些養(yǎng)護措施。由此可見,影響混凝土橋梁養(yǎng)護的因素是多元化的,這就說明了在對橋梁進行養(yǎng)護工作之前,我們必須全面分析影響橋梁養(yǎng)護效果的具體因素,并做出系統(tǒng)化、全局化的養(yǎng)護實施。而這正是現(xiàn)階段我國橋梁養(yǎng)護工作的薄弱之處,針對這一問題,本文結(jié)合武漢三環(huán)線五座橋梁的養(yǎng)護實踐經(jīng)驗,綜合分析三環(huán)線五座橋梁的養(yǎng)護數(shù)據(jù),尋求建立橋梁養(yǎng)護的前期病害分析、養(yǎng)護措施比選、養(yǎng)護方案的管理和性能評價的綜合體系。 本文首先在研究國內(nèi)外橋梁養(yǎng)護管理相關理論后得到了橋梁養(yǎng)護的定義、內(nèi)容以及方法,并針對武漢三環(huán)線五座橋梁提出了相對應的養(yǎng)護方法。針對武漢三環(huán)線五座橋梁的病害檢測,介紹混凝土橋梁病害調(diào)查和檢測方法,檢測的內(nèi)容,再結(jié)合三環(huán)線五座橋梁的病害進行病害原因分析和可能造成的影響進行分析。 其次,對橋梁的養(yǎng)護的基本定義、內(nèi)容、主要的預防性養(yǎng)護措施進行分析,提出有針對性的預防性養(yǎng)護措施,并引入實用性評價模型和經(jīng)濟性評價模型分別對預防性養(yǎng)護的實用性和經(jīng)濟性進行評價。 最后,依托武漢市三環(huán)線五座橋梁病害檢查項目,通過檢查獲取橋梁病害的的基本資料,探討橋梁病害機理,,進行橋梁病害的科學分類,對檢測結(jié)果進行分析和技術評狀況評價。同時本文針對橋梁技術狀況評價引入了馬爾可夫橋梁技術狀況預測模型,并對實例進行了分析和驗證。針對武漢市三環(huán)線五座橋梁提出養(yǎng)護措施,并構(gòu)建了完整的橋梁養(yǎng)護體系。
[Abstract]:With the steady development of transportation in our country, the number of bridges is increasing day by day, however, the bridge service life is longer in our country at the present stage, and the design standard is low, so the bridge damage is more serious.Therefore, it is very important to maintain the bridge in real time.Maintenance plays an important role in ensuring bridge performance and prolonging service life.This paper mainly studies the maintenance and management of five bridges on Wuhan third Ring Line, which are all reinforced concrete bridges.For reinforced concrete bridge, because of the physical and mechanical properties of reinforced concrete material, there will be some inevitable problems in the use of the bridge, these problems make the bridge need preventive maintenance work;As the structure and types of reinforced concrete bridges tend to be diversified, some maintenance measures are needed because of the damage of some structures.It can be seen that the factors affecting the maintenance of concrete bridges are diversified, which shows that before carrying out the maintenance work of bridges, we must comprehensively analyze the specific factors that affect the maintenance effect of bridges, and systematize them.The implementation of global maintenance.This is the weakness of the bridge maintenance work in our country at the present stage. In view of this problem, this paper synthetically analyzes the maintenance data of the third ring line and five bridges in combination with the practical experience of the maintenance of five bridges on the Wuhan third Ring Line.This paper seeks to establish a comprehensive system for the analysis of early stage diseases of bridge maintenance, the selection of maintenance measures, the management of maintenance schemes and the evaluation of performance.In this paper, the definition, content and method of bridge maintenance are obtained after studying the relevant theories of bridge maintenance and management at home and abroad, and the corresponding maintenance methods are put forward for five bridges of Wuhan third Ring Line.Aiming at the disease detection of five bridges in Wuhan third Ring Line, this paper introduces the investigation and detection methods of concrete bridge diseases, and then analyzes the causes and possible effects of the diseases of five bridges on the third Ring Line.Secondly, the basic definition, content and main preventive maintenance measures of bridge maintenance are analyzed, and corresponding preventive maintenance measures are put forward.The practicability and economy of preventive maintenance are evaluated by using practicability evaluation model and economic evaluation model respectively.Finally, relying on the inspection projects of five bridge diseases on Wuhan's third Ring Line, the basic information of bridge diseases is obtained, and the mechanism of bridge diseases is discussed, and the scientific classification of bridge diseases is carried out.Analyze the test results and evaluate the status of technical evaluation.At the same time, this paper introduces the Markov model for bridge technical condition evaluation, and analyzes and verifies the example.This paper puts forward maintenance measures for five bridges in Wuhan third Ring Line, and constructs a complete bridge maintenance system.
