中文摘要 | 地下水若處理不慎,重則造成開挖之失敗,輕則影響地下結構體之施工。本文由 實務面討論如何配合地下室之開挖抽除地下水,抽水作業基本上是以深水井搭配集水坑之方 式進行,但不同之地質狀況其搭配策略及井深、井數等皆有所不同。本文亦概略討論因抽水 引致之沉陷,及如何處理擋土結構之漏水。基本上地下水之處理是一門藝術,須參酌相關理 論及各地區之抽水經驗始能配置合理之抽水系統。 |
英文摘要 | If not properly taken care of, ground water is potentially hazardous to a basement excavation, as it may lead to excavation failure or jeopardize the construction of basement structure. This paper discusses how dewatering is carried out for basement excavation, the basic layout is to use deep wells and sumps in conjunction. It is noted that dewatering strategy varies in accordance with in situ soil condition, in order to obtain optimal dewatering performance, issues such as the layout of dewatering system, depth and number of wells must be carefully evaluated. Two relevant subjects, including dewatering related ground subsidence and possible schemes to seal off ground water leakage, are also addressed in this paper. Dewatering itself is an art in essence, the design of an appropriate dewatering system requires engineering judgement incorporating both theory and field experience. |
