發(fā)布時間：2018-12-18 07:03
【摘要】：傳統(tǒng)的DBB模式從組織層面上導(dǎo)致了設(shè)計與施工的分離,使得施工經(jīng)驗和知識無法有效應(yīng)用到設(shè)計中,會產(chǎn)生一系列的可施工性問題。整合設(shè)計與施工的組織模式,實施設(shè)計施工一體化管理是解決這一問題的首要條件。DB模式具有設(shè)計施工一體化的特點,可為具有豐富施工經(jīng)驗的人員參與到項目設(shè)計提供可能和便利,并為可施工性研究提供運行機制的保障,因此,基于DB模式下開展可施工性研究才具有更好的可操作性和實踐性。本文主要從DB總承包商的角度出發(fā),較深入研究了DB模式下建設(shè)項目設(shè)計階段的可施工性問題。1)闡述了可施工性的定義和分類,深入剖析了可施工性問題產(chǎn)生的具體原因,探討了可施工性研究的價值和重要性。2)總結(jié)了DB模式的設(shè)計概況,分析了DB模式下相比DBB模式下開展設(shè)計可施工性研究的優(yōu)勢和特點,重點對DB模式的初步設(shè)計和施工圖設(shè)計進行詳細(xì)研究,總結(jié)得出了影響初步設(shè)計可施工性和施工圖設(shè)計可施工性的主要影響因素。3)基于設(shè)計可施工性的影響因素,提出了四種改善DB項目設(shè)計可施工性的具體措施,并對如何實施上述措施進行了詳細(xì)的分析和說明。4)構(gòu)建了DB模式下初步設(shè)計方案和施工圖設(shè)計方案不同的可施工性評價指標(biāo)體系,結(jié)合模糊物元方法和組合權(quán)重思想建立了一種新的設(shè)計方案可施工性評價模型,并且通過工程實例應(yīng)用,體現(xiàn)了該模型的可行性和適用性。通過上述研究,為下一步改善項目設(shè)計方案的可施工性或創(chuàng)造新的設(shè)計方案提供了參考和借鑒,同時便于DB總承包商能夠定量進行自身不同設(shè)計方案的評價和優(yōu)選,其不僅豐富了DB模式下可施工性的研究內(nèi)容,也為進一步完善DB總承包制度和推動DB承發(fā)包模式在我國能更好的發(fā)展和應(yīng)用奠定了基礎(chǔ)。
[Abstract]:The traditional DBB model leads to the separation of design and construction from the organizational level, which makes the experience and knowledge of construction can not be effectively applied to the design, which will lead to a series of constructability problems. Integrating the organization mode of design and construction and implementing the integrated management of design and construction are the most important conditions to solve this problem. DB mode has the characteristics of integration of design and construction. May provide possibilities and facilities for the participation of persons with rich construction experience in the design of the project and provide safeguards for operational mechanisms for constructability studies, therefore, The research of constructability based on DB mode is more feasible and practical. From the point of view of the general contractor of DB, this paper deeply studies the constructability problem in the design stage of construction project under DB mode. 1) the definition and classification of constructability are expounded, and the concrete reasons for the problem of constructability are analyzed. This paper discusses the value and importance of constructability research. 2) summarizes the general design situation of DB mode, and analyzes the advantages and characteristics of DB mode compared with DBB mode to carry out design constructability research. The primary design and construction drawing design of DB mode are studied in detail, and the main factors influencing the constructability of preliminary design and construction drawing are summarized. 3) based on the influencing factors of design constructability, Four concrete measures to improve the constructability of DB project design are put forward. And how to carry out the above measures is analyzed and explained in detail. 4) the index system of constructability evaluation of the preliminary design scheme and the construction drawing design scheme under the DB mode is constructed. Combined with fuzzy matter-element method and combined weight idea, a new constructability evaluation model of design scheme is established, and the feasibility and applicability of the model are demonstrated by an engineering example. Through the above research, it provides a reference and reference for the next step to improve the constructability of the project design scheme or to create a new design scheme, and at the same time, it is convenient for the DB general contractor to evaluate and select their own different design schemes quantitatively. It not only enriches the research contents of constructability under DB mode, but also lays a foundation for further improving the general contracting system of DB and promoting the development and application of DB contracting mode in China.
