【摘要】：隨著時代的進(jìn)步,我國的高層建筑越來越多,為了確保建筑的牢固,建筑基礎(chǔ)都要滿足地基基礎(chǔ)的相關(guān)要求,因此,基坑工程的重要性也越來越明顯�；庸こ�,是指在地層下面開挖的一個整體的支護(hù)保護(hù)體系。而基坑支護(hù),就是為確保地下結(jié)構(gòu)施工及基坑周邊環(huán)境安全,對基坑側(cè)壁及周邊環(huán)境采取適當(dāng)?shù)闹ёo(hù)、加固與保護(hù)措施。由于我國地域遼闊,土層情況各不相同,因此,基坑支護(hù)作為臨時性工程,根據(jù)各個地區(qū)不同的特點(diǎn),選用符合當(dāng)?shù)貤l件的支護(hù)形式。基坑開挖不僅要考慮基坑自身的安全性能,同時也要保證基坑周邊建筑物及土層等在有效的控制范圍之內(nèi)。本文以德爾國際絲綢博覽中心基坑支護(hù)工程為研究對象,了解該工程的概況,根據(jù)該工程的特點(diǎn)進(jìn)行基坑支護(hù)設(shè)計(jì)的分析研究,確定經(jīng)濟(jì)可行的組合式支護(hù)形式,進(jìn)一步通過計(jì)算復(fù)核設(shè)計(jì)的安全性,根據(jù)設(shè)計(jì)制定土方開挖的工序和方案,根據(jù)現(xiàn)場布置合理的基坑檢測方案,通過監(jiān)測的數(shù)據(jù)來反映基坑和周邊建筑、管線等變形情況,對設(shè)計(jì)起到校核作用,對施工起到指導(dǎo)作用。綜合分析表明,本工程通過理論設(shè)計(jì)和施工實(shí)際的檢驗(yàn),證明該基坑圍護(hù)的方式是可行的,該方案確�；雍椭車ㄖ姆�(wěn)定。本文的研究成果對相類似的工程有一定的參考價值。
[Abstract]:With the progress of the times, there are more and more high-rise buildings in our country. In order to ensure the stability of the building, the building foundation must meet the related requirements of the foundation. Therefore, the importance of the foundation pit engineering is becoming more and more obvious. Foundation pit engineering refers to a whole support and protection system which is excavated under the stratum. In order to ensure the underground structure construction and the surrounding environment safety of the foundation pit, the foundation pit support is to take appropriate support, reinforcement and protection measures to the side wall and the surrounding environment of the foundation pit. Because of the vast area and different soil conditions in our country, the foundation pit support as a temporary project, according to the different characteristics of each area, select the supporting form which accords with the local conditions. In the excavation of foundation pit, not only the safety performance of the foundation pit itself should be considered, but also the building and soil layer around the foundation pit should be kept within the effective control range. In this paper, the foundation pit support project of Del International Silk Expo Center is taken as the research object, and the general situation of the project is understood. According to the characteristics of the project, the analysis and research of the foundation pit support design are carried out, and the economical and feasible combined support forms are determined. Furthermore, the safety of the design is calculated, the working procedure and scheme of earthwork excavation are worked out according to the design, the reasonable foundation pit detection scheme is arranged on the spot, and the deformation of foundation pit and surrounding buildings and pipelines are reflected by monitoring data. It has the function of checking the design and guiding the construction. The comprehensive analysis shows that the method of retaining foundation pit is feasible through theoretical design and practical test, and this scheme ensures the stability of foundation pit and surrounding buildings. The research results of this paper have certain reference value for similar projects.
