  本文選題：SMW工法樁 + 基坑支護(hù)��； 參考：《西安建筑科技大學(xué)》2015年碩士論文

【摘要】：SMW工法是一種從國(guó)外引進(jìn)的比較新穎的基坑支護(hù)施工工藝,我國(guó)最先于上世紀(jì)九十年代初通過技術(shù)引進(jìn),并在上海環(huán)球世界商廈基坑圍護(hù)中首先得到成功應(yīng)用。由于SMW工法工藝簡(jiǎn)單、工期短、造價(jià)低、節(jié)約鋼材、節(jié)約地下空間資源、安全可靠等優(yōu)點(diǎn),符合國(guó)家建設(shè)節(jié)約型社會(huì)和發(fā)展循環(huán)經(jīng)濟(jì)需要,在上世紀(jì)九十年代末被建設(shè)部列為重點(diǎn)推廣項(xiàng)目。此后得到了大量推廣應(yīng)用。本文正是在此背景下,針對(duì)GCL商住樓項(xiàng)目基坑支護(hù)開展應(yīng)用研究。論文首先對(duì)一般基坑支護(hù)的類型、基本概念、特點(diǎn)、應(yīng)用以及研究現(xiàn)狀等理論知識(shí)進(jìn)行了介紹,特別是對(duì)SMW工法樁的工藝原理、施工工藝流程、施工要點(diǎn)進(jìn)行了介紹。本文以GCL商住樓項(xiàng)目基坑支護(hù)作為研究對(duì)象,首先介紹了項(xiàng)目的地質(zhì)情況、支護(hù)形式、支護(hù)做法、支護(hù)控制原則、施工和監(jiān)測(cè)要求。然后對(duì)不同類型圍護(hù)結(jié)構(gòu)的特點(diǎn)進(jìn)行了對(duì)比分析,論證了本項(xiàng)目所采用的SMW工法樁支護(hù)方案經(jīng)濟(jì)、先進(jìn)、合理。最后為項(xiàng)目設(shè)計(jì)了基坑支護(hù)的項(xiàng)目管理體系,確定了相應(yīng)的項(xiàng)目管理組織,制定了主要資源需求計(jì)劃,明確了項(xiàng)目管理目標(biāo),并進(jìn)行了施工總體部署。本文最后針對(duì)SMW工法樁施工方案的圍護(hù)體系和支撐體系進(jìn)行了具體研究,包括對(duì)圍護(hù)結(jié)構(gòu)的表面處理、基坑土方挖運(yùn)、基坑排水、基坑監(jiān)測(cè)、坑中坑的處理以及內(nèi)支撐最后的拆除等進(jìn)行了施工技術(shù)總結(jié)。并為達(dá)到基坑支護(hù)施工質(zhì)量管理目標(biāo),制定了項(xiàng)目質(zhì)量目標(biāo)管理制度、質(zhì)量和安全及工期保證措施,以確�；邮┕べ|(zhì)量能達(dá)到本項(xiàng)目管理目標(biāo)。最后通過近5個(gè)月的第三方獨(dú)立監(jiān)測(cè)檢驗(yàn),驗(yàn)證了該基坑支護(hù)變形滿足設(shè)計(jì)要求,為后續(xù)主體工程順利推進(jìn)提供了工期、質(zhì)量、安全保障。論文結(jié)論有利于SMW工法樁基坑支護(hù)項(xiàng)目的開展,有助于實(shí)現(xiàn)項(xiàng)目目標(biāo),也為后續(xù)工程提供經(jīng)驗(yàn)借鑒。
[Abstract]:SMW method is a relatively novel foundation pit support construction technology introduced from abroad. It was first introduced in China at the beginning of 1990s, and it was first successfully applied in the foundation pit protection of Shanghai Universal Commercial Building. Due to the advantages of simple process, short construction period, low cost, saving steel, saving underground space resources, safety and reliability, the SMW process meets the needs of the country to build a conservation-oriented society and to develop a circular economy. In the last century in the late 90 s by the Ministry of Construction as a key promotion project. Since then has been a large number of applications. Under this background, this paper studies the application of foundation pit support for GCL commercial and residential building project. This paper firstly introduces the types, basic concepts, characteristics, applications and research status of general foundation pit support, especially introduces the technological principle, construction process and construction essentials of SMW pile. In this paper, the foundation pit support of GCL commercial and residential building project is taken as the research object. Firstly, the geological conditions, supporting forms, supporting methods, supporting control principles, construction and monitoring requirements of the project are introduced. Then the characteristics of different types of retaining structures are compared and analyzed, and the SMW pile support scheme adopted in this project is proved to be economical, advanced and reasonable. Finally, the project management system of foundation pit support is designed, the corresponding project management organization is determined, the main resource demand plan is worked out, the project management goal is defined, and the overall construction arrangement is carried out. In the end of this paper, the construction system and support system of SMW pile are studied, including the surface treatment of retaining structure, excavation and transportation of foundation pit, drainage of foundation pit, monitoring of foundation pit, etc. The treatment of the pit in the pit and the final demolition of the inner support are summarized. In order to achieve the goal of foundation pit supporting construction quality management, the project quality target management system, quality and safety measures and time limit guarantee measures are established to ensure that the foundation pit construction quality can reach the project management goal. Finally, through the third party independent monitoring inspection for nearly 5 months, it is verified that the foundation pit support deformation meets the design requirements, and provides a guarantee for the construction period, quality and safety of the subsequent main project. The conclusion of the paper is beneficial to the development of SMW pile and foundation pit support project, to the realization of project objectives, and to provide experience for subsequent projects.
