【摘要】：基坑開挖是一項復(fù)雜性工程,尤其是深基坑開挖,它涉及土力學(xué)、水力學(xué)、結(jié)構(gòu)力學(xué)、材料力學(xué)等眾多學(xué)科,它既需要研究土力學(xué)中的強度、穩(wěn)定和變形等問題,也需要解決支護和降水止水等問題。此外,開挖基坑以及后續(xù)的支護、降止水所花費的費用相當(dāng)高。這就需要基坑設(shè)計人員以及施工人員要依照工程的實際情況,運用合理的方法,充分考慮基坑的開挖、支護、降止水等問題,使其不但在設(shè)計施工上合理,而且在經(jīng)濟上也能減少成本。 本文結(jié)合丹東港5萬噸級散貨泊位工程-翻車機小區(qū)工程,總結(jié)深基坑工程在軟土深基坑支護中的應(yīng)用,根據(jù)工程實際情況,經(jīng)方案對比,采用地下連續(xù)墻基坑支護和止水,計算地下連續(xù)墻的嵌固深度,驗算其穩(wěn)定性,基坑側(cè)壁的變形觀測結(jié)果表明,采用地下連續(xù)墻支護和止水效果良好。 大量的基坑建設(shè)經(jīng)驗表明,工程的設(shè)計和施工緊密相聯(lián),融為一體。施工的每個環(huán)節(jié),都會引起基坑的內(nèi)部結(jié)構(gòu)和外部荷載發(fā)生不同程度的改變,也就使得在選用不同的施工工藝時需進行仔細(xì)研究論證。據(jù)此,本文對基坑工程的支護和降止水研究有著重要的理論意義和現(xiàn)實意義。
[Abstract]:Excavation of foundation pit is a complex engineering, especially deep foundation pit excavation. It involves many subjects such as soil mechanics, hydraulics, structural mechanics, material mechanics and so on. It needs to study the strength, stability and deformation of soil mechanics. It is also necessary to solve the problems of supporting and water stopping. In addition, excavation of foundation pit and subsequent support, the cost of reducing water is quite high. Therefore, it is necessary for foundation pit designers and construction personnel to apply reasonable methods to fully consider the problems of excavation, supporting, lowering and sealing of foundation pit in accordance with the actual conditions of the project, so that it is not only reasonable in design and construction, but also in the design and construction of the foundation pit. And it can also reduce costs economically. In this paper, the application of deep foundation pit engineering in soft soil deep foundation pit support is summarized. According to the actual situation of the project, the underground continuous wall foundation pit is used to support and stop water, according to the actual situation of the project. By calculating the embedded depth and checking the stability of the underground continuous wall, the deformation observation results of the side wall of the foundation pit show that the underground continuous wall supports and stops the water well. A large number of foundation pit construction experience shows that the design and construction of the project are closely linked and integrated. Each link of construction will cause the internal structure and external load of foundation pit to change to different degrees, which makes it necessary to study and demonstrate carefully when selecting different construction technology. Therefore, this paper has important theoretical and practical significance to the research of foundation pit engineering supporting and reducing water stop.
