大朝山水電站大壩基礎防滲帷幕灌漿設計與施工Gin is the abbreviation for grouting intensity number. it is showed by the product of the final grouting pressure p ( unit : mpa ) on the grouting section and the grouting volume v ( unit : l / m ) on every one meter of the grouting section, which means the energy consumed on every one meter of grouting section. according to gin method, if during the grouting construction, same energy is consumed on every grouting section, i. e. gin keeps to be a constant, an approximately uniform impervious curtain can be obtained
Gin （ groutingintensitynumber ）即灌漿強度值，它用灌漿孔段上最終的灌漿壓力p （ mpa ）和單位灌漿段長度漿液灌注量v （ l / m ）的乘積表示，其含義為單位灌漿段上消耗的能量， gin法灌漿認為在灌漿施工中，保持各灌漿孔段上消耗一致的能量，即保持gin為常數，便可形成一道大致均勻的防滲帷幕。Combining achievements in past scientific research, this thesis summarizes some problems in the process of decreasing water, the problems contains : important parameters such as percolation coefficient, interfering radius etc ; designers get parameters from their experience and make their choice of limited prospecting materials too simply, because of the limits, designer ca n ' t make quantitative analysis on groundwater ; differences on breakwater effect of setting water - tight screen is still existed, although research evolvement in this field is done ; they ca n ' t grasp the hydrogeology parameters accurately in that it influences rightness of designing in deep excavation water - decreasing
本文結合以往的研究成果，總結了降水過程中存在的一些問題，主要包括：重要設計參數，如地層滲透性、基坑降水影響半徑等，設計中僅從個人經驗出發取值，對有限的勘探資料進行取捨和過分地簡化。這些局限使設計者不能對地下水進行科學的定量分析，盲目性較大；深基坑降低承壓水引起的周邊地面沉降的研究雖已取得很大的進展，但是一些主要問題仍未解決，對防滲帷幕的實際擋水效果存在不同看法；對於弱透水層的水文地質參數一直難以準確把握，影響了深基坑降水設計的正確性。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。For example, after the collapse of ditong dam in idaho, may 5, 1976, it was found that it was not impervious very well, the impervious curtain was built poorly. when the seepage went through the impervious curtain, the exit water from the pervious material of the downstream or the right side of dam through the foundation or certain line between the foundation and the dam caused contact scour and piping
如美國愛得華州提堂壩於1976年5月5日潰決，事後調查分析，因壩基透水性大，防滲帷幕施工質量差，滲流穿透帷幕，經地基或地基與壩的接觸面從壩體下游側透水料區逸出或從右壩肩繞滲經下游壩體逸出，出逸的水流引起了接觸沖刷和管涌，導致潰壩。Some conclusions are drawn and suggestions put forward, which provide a good basis for safe operator of dam. fourthly, with the optimized seepage coefficient, the seepage state of dongzhang dam foundation and effect of grouting are appraised by comparing several different seepage control schemes, and then some seepage control measures are concluded
