【正文】 河北工程大學(xué)畢業(yè)設(shè)計(jì) (論文 ) I 頤和佳苑基坑支護(hù)工程設(shè)計(jì) 摘要 隨著城市建設(shè)的發(fā)展，高層建筑越來越多，出現(xiàn)了大量的深基坑工程。 本次設(shè)計(jì)內(nèi)容為現(xiàn)代 頤和佳苑基坑支護(hù)工程設(shè)計(jì)。 該基坑開挖深度達(dá) 10m，場(chǎng)地土層厚度約 11m，多為素填土、紅粘土 。 地下水、地表水豐富，工程地質(zhì)條件復(fù)雜?；又車薪ㄖ铩⒌缆?、地下管道、電纜線等，環(huán)境條件復(fù)雜。為了保證基坑周圍的建筑物、地下管線、道路等的安全和基坑邊坡的穩(wěn)定，必須對(duì)該 深 基坑進(jìn)行 支護(hù)設(shè)計(jì) 。 最終本次設(shè)計(jì)采用 土釘墻支護(hù)和樁 錨支護(hù) ， 這樣 既能保證基坑四周邊坡的穩(wěn)定性，保證施工現(xiàn)場(chǎng)有足夠的空間，又起到擋土的作用， 保證周圍建筑物和地下設(shè)施安全，同時(shí)設(shè)計(jì)方案具有較好的技術(shù)經(jīng)濟(jì)性。 關(guān)鍵詞： 基坑支護(hù) ；土釘墻； 樁錨 支護(hù) 河北工程大學(xué)畢業(yè)設(shè)計(jì) (論文 ) II Abstract (1)Along with the development of city building,high building are more and more,appearing a foold of deep excavation engineering projects. (2)The main content of the design is foundation pit support for XiandaiYihejiayuan. (3)(The depth of digging the foundation pit amount 10m, the soil layer thickness roughly 11m,which is a plain fill soil, red clay.(4) Groundwater and surface water is plentiful, that results in plicacy of engineering geology condition. （ 5）Environment condition plicacy results of the foundation pit surrounding building,road,underground piping,cable etc.) (6)For safety of the surround buildings, underground tube line, road and other aspects during excavation and stability of the slope of excavation, it is necessary to design pit support scheme for the deep foundation pit.(7) [Ultimately, I adopted soil nail wall and pile–anchor ,because this scheme can guarantee the pit stability of all sides and has the good technical efficiency. ] Key words: Pit Support。 soil nail wall。 pile–anchor support A1: background Sentence 1 A2: main topic Sentence 2 A3: specific investigation Sentence 5 A4: suggestion Sentence 6 A5: conclusion Sentence 7 河北工程大學(xué)畢業(yè)設(shè)計(jì) (論文 ) I 目 錄 前言 ..................................................................................................................
