【摘要】：密肋復(fù)合墻結(jié)構(gòu)是一種節(jié)能、抗震的新型裝配整體式建筑結(jié)構(gòu)體系，針對該結(jié)構(gòu)體系課題組前期在理論及應(yīng)用研究方面開展了大量的工作，其結(jié)構(gòu)設(shè)計理論基本趨于成熟，進入了推廣階段，在地震設(shè)防烈度較高的黃土地區(qū)已得到較好的應(yīng)用。然而，作為一種新型的結(jié)構(gòu)體系，在黃土地區(qū)的推廣過程中存在著較多的不確定性因素，影響該結(jié)構(gòu)體系的進一步應(yīng)用，且相關(guān)研究中較少涉及不確定性風(fēng)險因素。為此，本文主要就以下內(nèi)容進行重點研究： （1）綜合考慮密肋復(fù)合墻結(jié)構(gòu)構(gòu)造特點及設(shè)計要求，對黃土地區(qū)已建項目與在建項目進行現(xiàn)場調(diào)研，分析總結(jié)施工工藝的關(guān)鍵技術(shù)及相關(guān)要求。為該結(jié)構(gòu)體系及其它裝配式結(jié)構(gòu)的施工建造提供參考，并為進行黃土地區(qū)密肋復(fù)合墻結(jié)構(gòu)體系風(fēng)險因素的識別奠定專業(yè)基礎(chǔ)。 （2）通過對多種風(fēng)險分析方法的比較研究，提出適合密肋復(fù)合墻結(jié)構(gòu)體系風(fēng)險分析的研究方法，并基于模糊數(shù)學(xué)及層次分析法原理建立相應(yīng)的風(fēng)險分析模型。為進行黃土地區(qū)密肋復(fù)合墻結(jié)構(gòu)體系的風(fēng)險分析奠定理論基礎(chǔ)，也為課題組以后對該結(jié)構(gòu)體系進行更為深入的風(fēng)險分析研究提供相應(yīng)的參考方法。 （3）通過對各方相關(guān)專家的調(diào)查咨詢，將黃土地區(qū)密肋復(fù)合墻結(jié)構(gòu)體系全壽命周期中所特有的主要風(fēng)險因素分為相互關(guān)聯(lián)、相互影響的決策階段、實施階段和使用階段風(fēng)險來進行識別；并運用建立的風(fēng)險分析模型對其進行全面分析，得出決策階段和實施階段的綜合風(fēng)險較大；其中，相關(guān)政策、社會認(rèn)可度、墻板設(shè)計、施工工序復(fù)雜等具體風(fēng)險因素所占比重較大，是進行風(fēng)險評估與控制時重點考慮的對象。分析結(jié)果可為進行黃土地區(qū)密肋復(fù)合墻結(jié)構(gòu)體系風(fēng)險管理，從而減小其風(fēng)險度，促進該結(jié)構(gòu)體系的發(fā)展應(yīng)用與相關(guān)規(guī)范的制定，提供科學(xué)依據(jù)，，具有一定的現(xiàn)實意義。
[Abstract]:Multi-ribbed composite wall structure is a new type of energy-saving, earthquake-resistant, integrated building structure system. A lot of work has been done on the theory and application of this structure system research group in the early stage, and its structure design theory tends to mature basically, and the structure design theory of the multi-ribbed composite wall structure is almost mature. In the period of popularization, it has been applied well in the loess area with high earthquake fortification intensity. However, as a new type of structural system, there are more uncertain factors in the process of popularizing the loess area, which affect the further application of the structural system, and less uncertainty risk factors are involved in the related research. Therefore, the main contents of this paper are as follows: (1) considering the structural characteristics and design requirements of multi-ribbed composite wall, on-the-spot investigation of existing and under-built projects in loess area is carried out. The key technology and related requirements of construction technology are analyzed and summarized. It provides a reference for the construction of the structural system and other assembled structures, and lays a professional foundation for identifying the risk factors of the multi-ribbed composite wall structure system in the loess area. (2) through the comparative study of various risk analysis methods, the risk analysis method suitable for multi-ribbed composite wall structure system is put forward, and the corresponding risk analysis model is established based on the principles of fuzzy mathematics and analytic hierarchy process (AHP). It lays a theoretical foundation for the risk analysis of the multi-ribbed composite wall structure system in loess area, and also provides a reference method for the further risk analysis and study of the multi-ribbed composite wall structure system in the future. (3) through the investigation and consultation of relevant experts from all parties, the main risk factors in the life cycle of multi-ribbed composite wall structure system in loess area are divided into interrelated and influencing decision-making stages. Risk identification during the implementation phase and the use phase; And using the established risk analysis model to carry on the comprehensive analysis to it, obtains the decision-making stage and the implementation stage comprehensive risk is relatively large; Among them, the relative policies, social recognition, wallboard design, complex construction process and other specific risk factors account for a large proportion, which is the focus of risk assessment and control. The analysis results can provide scientific basis for the risk management of multi-ribbed composite wall structure system in loess area, so as to reduce its risk degree, promote the development and application of the structure system and the formulation of relevant norms, and have certain practical significance.
