【摘要】：改革開放以來,經(jīng)濟迅速增長,我國建筑業(yè)取得了長足的發(fā)展。各城市中的高層建筑、地鐵車站的不斷涌現(xiàn),促進了基坑工程迅速增多,規(guī)模越來越大,開挖深度越來越深。而基坑工程具有工程量大、挖深大、形式復(fù)雜、施工難度大、環(huán)境干擾因素多等特點,在施工過程中,施工單位將面臨著各種因素引起的施工質(zhì)量風(fēng)險。因此研究基坑工程施工質(zhì)量風(fēng)險管理,有助于預(yù)防和減少質(zhì)量事故的發(fā)生。本文以“基坑工程施工質(zhì)量風(fēng)險管理”為研究對象,進行了以下的研究。 (1)分析了目前國內(nèi)外工程質(zhì)量管理和風(fēng)險管理的現(xiàn)狀,提出了基坑工程施工質(zhì)量風(fēng)險管理的研究意義。 (2)探討了基坑工程施工質(zhì)量風(fēng)險管理的理論及其特點,構(gòu)建了基坑工程施工質(zhì)量風(fēng)險管理流程,分析了質(zhì)量風(fēng)險的評價方法。 (3)結(jié)合對基坑工程施工質(zhì)量的特點及質(zhì)量風(fēng)險的形成過程,分析了影響基坑工程施工質(zhì)量風(fēng)險的主要因素是人、材料、方法、機械和環(huán)境,建立了基坑工程施工質(zhì)量風(fēng)險評價指標(biāo)體系及質(zhì)量風(fēng)險評價模型。 (4)以湖南省電力公司調(diào)度通信樓的基坑工程為實例,分析了影響基坑工程施工質(zhì)量的因素,將模糊層次綜合評價法建立的模型對具體基坑工程進行應(yīng)用,判定評價風(fēng)險等級,并提出對該工程的質(zhì)量風(fēng)險控制措施。
[Abstract]:Since the reform and opening up, rapid economic growth, China's construction industry has made considerable development. The continuous emergence of high-rise buildings and subway stations in various cities has promoted the rapid increase of foundation pit engineering, the larger the scale and the deeper the excavation depth. The foundation pit engineering has the characteristics of large amount of engineering, deep excavation, complex form, difficult construction and many environmental interference factors. In the process of construction, the construction unit will face the construction quality risk caused by various factors. Therefore, the study of foundation pit construction quality risk management is helpful to prevent and reduce the occurrence of quality accidents. In this paper, "Foundation pit construction quality risk management" as the research object, carried out the following research. The main contents are as follows: (1) the present situation of project quality management and risk management at home and abroad is analyzed, and the significance of research on risk management of foundation pit construction quality is put forward. (2) the theory and characteristics of quality risk management in foundation pit construction are discussed, the risk management flow of foundation pit construction quality is constructed, and the evaluation method of quality risk is analyzed. (3) combined with the characteristics of foundation pit construction quality and the forming process of quality risk, the main factors influencing the quality risk of foundation pit construction are people, materials, methods, machinery and environment. The quality risk evaluation index system and quality risk evaluation model of foundation pit construction are established. (4) taking the foundation pit engineering of the dispatching communication building of Hunan Electric Power Company as an example, the factors influencing the construction quality of the foundation pit engineering are analyzed. The model established by the fuzzy hierarchy comprehensive evaluation method is applied to the concrete foundation pit project and the risk grade is evaluated. The quality risk control measures of the project are put forward.
