摘要某碼頭工程在採用圍堰進行岸坡開挖過程中,受江水和地下水位的影響,基坑內有水滲入導致工程無法進行。Based on nonlinear finite element theory, stress and deformation behaviors are analyzed after ground stabilization and foundation pit reinforcement with deep mixing method. by comparison of the conditions of treatment and non - treatment of two examples respectively, the results indicate that the match ratio scheme used for deep mixing method is more ideal when soft clay is stabilized in this area of fuzhou in the thesis. this scheme not only can fully utilize industrial waste material, but also can economize construction cost
對于加固土的工程特性,本文以非線性有限元理論為基礎,模擬分析水泥攪拌樁加固地基和基坑支護加固的應力和變形情況;通過兩個例子分別在有處理和無處理情況下的對比,利用固化劑最佳摻入比來設計地基處理方案,並運用非線性有限元方法計算出土體內大小主應力的分佈情況以及變形情況,結果表明本文所得出的配合比方案用於深層攪拌樁法來對福州地區軟粘土進行地基加固時還是比較理想的,這樣不僅充分利用工業廢料,還可節約工程造價。It is most unusual that they stand at least a kilometre from the sea, unlike other rock carving in hong kong although they still overlook a small expanse of water, i. e. the stream running below them
香港石刻多分佈於海濱地區。黃竹坑石刻則深入內陸約一公里,但下有小溪流經,仍可算臨近水邊。The nancha suspending - gay bridge of the changjiang road - bridge in jiangshu runyang, with a main span of 1490m, ranks first in china, third in the world. the north rivets, only 250m from the main stream of changjiang, have a tight liaison with the waterpower of it. especially, in this area, the face of rocks undulates a lot and exist fault - fabric. the soil there has apparent difference with the trend of water. the base - hole of north rivets can be named a super - deep one, with a 60m length, 50m widths, and 48m depths. the fence of the base takes advantages of the rectangular underground continuous wall structure and succeeds
江蘇潤揚長江公路大橋南汊懸索橋,主跨1490m ,居中國第一,世界第三。該橋的北錨碇距長江幹流僅250m ,與長江水力聯系密切,錨碇區水文、地質情況復雜,表層淤泥質土及松軟粘土層較厚,基巖頂面起伏較大,且存在斷裂構造,土層具明顯的流變特性。北錨碇基坑為長60m 、寬50m 、深48m的矩形超深基坑,其基礎圍護在國內首次採用矩形地下連續墻結構,並獲得成功。As a whole, the research work of this dissertation can be summarized as follows : ( 1 ) based on the porous media elastic unstable theory, the interfering well flow model of soft soil two - layer structure underground confined water is inferred, and consequently, the basic dewatering calculation method of soft - soil two - layer deep excavation dewatering is inferred
具體研究內容如下: (一)從彈性多孔介質滲流理論出發,推導出二元結構承壓含水層群井干擾穩定流模型,進而導出軟土地區二元結構地層深基坑降水的基本計算方法。Through the analysis and calculation the conclusion can be made that during the process of the timbering of excavation, the magnitude of soil stress decreases with the increase of the displacement on the base of the still earth pressure, and the earth pressure distribution varies from the triangular distribution of the still earth pressure to other distribution with the displacement of the timbering structure. the thesis introduces the bedding coefficient in the horizontal direction varying with the soil displacement from soil - structure interaction mode, therefore calculation can be made to get more rational calculation result using elastic foundation finite element method which is the same to timbering structure both upwards and under excavation surface
通過分析計算可以得出,在基坑支護過程中,土壓力的大小在靜止土壓力值的基礎上隨支護結構向坑內側位移增大而減小;土壓力的分佈由靜止土壓力的三角形分佈隨支護結構位移變化成其它分佈;由土-結構共同作用模式引入隨土體位移變化的水平向基床系數,使支護結構在開挖面以上部分同以下部分一樣,均可採用彈性地基有限元法進行計算,得出更為合理的計算結果。The thesis makes model experiment on imminent problems existed in deep excavation water - decreasing project, the concrete contents is as follows : ( 1 ) soft soil two - layer structure stratum is simulated, deep excavation water - decreasing model test is carried on and the law of water motion is observed depending on precise instruments
就深基坑降水工程實際中出現的急待解決的問題進行了大量的試驗研究,具體研究內容如下: (一)在實驗室模擬軟土地區二元結構地層,進行深基坑降水模型實驗,觀察地層承壓地下水水流運動狀態和運動規律。Based on the characteristics of the foundation for the powerhouse of chaozhou water supply control project, the supporting measures, excavation method and control measures for the foundation excavation is put forward herein, and then the method to solve the problems such as monitoring on the supporting, de - pressurization of the ground water, treatment of the seepage from the outside and the protection of the structures inside of the foundation pit etc. are presented as well
