中文拼音 [bèishuǐwéimù]
排水帷幕
英文
drainage curtain-
The finite element analysis of 3d seepage field for surrounding rock mass of cavern groups of underground powerhouses was performed based on the nodal virtual flux method for solving the non - pressure seepage field and the improved drainage substructure technique for accurately simulating the complex seepage behaviors of densely distributed drainage holes, with emphasis placed on the seepage properties of the anti - seepage concrete curtain and drainage curtain in the anti - seepage and drainage system
摘要在求解無壓滲流場結點虛流量法的基礎上，結合可精細模擬密集排水孔復雜滲流水力行為的改進排水子結構技術，付某地下廠房廠區洞室群圍巖區三維滲流場進行了有限元求解分析，著重研究了防滲排水系統中的帷幕和排水幕的滲流特性。The distance of the single - row curtain grout hole is between 1. 4 to 1. 8 meter, and 2. 0 meter is suitable for the double - row curtain ; the grouting pressure generally is 1. 0 to 1. 5 mpa at the first three grout compartment, then grouting pressure of under the fourth control in 4 to 5 mpa ; for mast grout compartments, a water - cement ratio of 2 or 1 may used in the first grouting
鉆孔密度也由原來的0 . slm / mz降至o . 64n擴mz ，節約工程投資447 . 35萬元。 6 、單排帷幕的孔距在1 . 4一1 . 8m之間，雙排帷幕的孔距以zm為宜;灌漿壓力在地表以下前三段一般為1一1 . smpa ，第四段以下按4一smpa控制;對大部分孔段而言，開灌水灰比可定為2或1 。Through analyzing the seepage observation data of huangtankou concrete gravity dam, foundation seepage behavior are reasonably evaluated. the reason of seepage force rising of individual monolith is impervious elements " flaw and drain holes " block. 4
分析黃壇口大壩壩基滲流監測資料，正確評價了壩基防滲排水系統的工作狀態，指出了個別壩段滲透壓力升高是由於壩基防滲帷幕缺陷和排水孔被堵造成，為工程加固提供了科學依據。Complicated hydrologic and geographic conditions, and the large scale of the xiaolangdi hydraulic project on the yellow river are introduced briefly. three desilting tunnels are designed to meet the requirements of flood control, sediment discharge and runoff regulation. according to the performance requirements of desilting tunnels, the tunnel lining down - stream of the grouting curtain is designed to be post - tensional prestressed lining. on the basis of investigation and research, experiements and analysis, the unbonded prestressing system is used. it is the largest unbonded prestressed tunnel lining project in the world, and the first one in china
簡介黃河小浪底水利樞紐復雜的水文、地質條件以及龐大的工程規模.該樞紐設計有3條排沙洞，擔負著泄洪、排沙、調節徑流和保證進水口不被泥沙淤堵的任務.根據排沙洞的水庫運用要求，灌漿帷幕下游排沙洞洞身段設計為混凝土后張預應力隧洞.通過大量的調研、試驗、分析論證，在施工前確定該預應力方案選用無粘結預應力系統，成為目前世界上規模最大的無粘結預應力隧洞襯砌工程，在國內尚屬首例Through the practice of deep foundation top - down for youyou international square, some key construction techniques were introduced, including structure of bored and double stirring piles, down - top construction in high - rise buildings, top - down in low - rise buildings, protection of railways, methods for excavation
摘要通過由由國際廣場深基坑逆作施工實踐，著重介紹了灌注樁加雙排攪拌樁止水帷幕圍護體系、主樓順作裙房逆作、電纜翻交、軌道交通四號線保護、挖土施工等關鍵施工技術。Some key subjects of numeric analysis were discussed such as : selecting principles of constitutive equations of soft clay, the equivalent theory of vertical drains ground, the definition of load step, the determination of vertical drains as well as the treatment methods of the decline of groundwater level, sealing wall and nearby water source
著重論述了真空預壓加固地基數值分析中對土體本構方程的選擇、砂井地基等效轉換、分析荷載步的確定、豎向排水體的界定、地下水下降的處理、密封帷幕的處理、附近補充水源的處理等問題。分享友人
