中文摘要 | 於地下結構物之深開挖工程中,傳統上一直是使用皂土穩定液,作為地下連續施 工時穩定壁面與防止開挖壁面崩塌之材料。然而皂土穩定液所造成的大量廢泥漿,卻經常 成為工程界相當困擾的問題。皂土廢液不僅數量龐大,且運棄費用昂貴:而最為甚者,便 是其將造成環境嚴重污染及二次公害等問題。 近年來,國內外相繼開發出數種以長鏈有機高分子聚合物為主的皂土代用品作為穩 定液,且以其作為穩定液應用於連續壁施工在國內外亦已有許多成功案例,然而對此種 高分子聚合物穩定液之特性,及其組成,功能和穩定原理,以至於影響該穩定液效能的各 種因素,在目前卻甚少有學者加以研究。 故本文針對上述各項目進行相關研究,使高聚合物穩定液在連續壁工程上之應 用能更有所依據,並使施工者得以預先避免不利於此種穩定液在使用效能上之種種響因 素,期以提升國內連續壁工程之品質。 |
英文摘要 | Sturry wall has been used throughout the world in three decades. It is an excavation in unstable soil supported by a fluid which is constantly kept at the ground level, later backfilled with an engineered substance. For the last thirty years, bentonite slurry is used in almost every trench excabation to stabilize the trench walls. Althouth bentonite slurry has been used to stabilize the deep trench widely in the world, but there are some problems in using bentonite fluid. The use of a fluid exists in the form of a synthetic low molecular weight cellulosic polymer formulation combined with a colloidal mineral suspension can solve problems resulted from using bentonite slurry. In this research, (1) why is the bio-polymer slurries, and how can bio-polymer behavior in slurries be explained;(2) what factors affect bio-polymer slurry properties; and (3) what factors affect bio-polymer slurry performance will be studied. After that, the use of bio-polymer slurry for stabilizing deep excavation can be specified, and the quality of slurry wall construction can be improved by using bio-polymer slurry as a stabilizer. |
