摘要(中) |
本研究將膠結物質加入砂質土壤中,依照其加入膠結物含量(重量比)、種類、養護齡期,探討其抗液化能力與液化後的沈陷量,並量測其透水性質與液化之間的關係,以作為分析討論之依據,期提供台灣地區震災液化相關之應用。 研究結果顯示砂質土壤膠結材料含量越高,試體滲透係數κ越小,加入含量12%的水泥漿後試體的滲透係數κ相較於未加入膠結材料試體降低了99%;加入含量12%的水玻璃試體滲透係數κ降低了93%。本研究以液化影響因子K(t)評估土壤抗液化能力,試體齡期28天時,水泥漿含量12%的試體其液化影響因子為未加入膠結物試體的225倍,相當於MMS震動級數(美國地震震度分級)由7+提升到9+;水玻璃含量12%的試體其液化影響因子為未加入膠結物試體的458倍,相當於MMS震動級數由7+提升到10+。膠結物含量越高,試體液化沈陷量越小,試體齡期28天時,含量12%的水泥漿(水灰比1:1)試體液化後沈陷量降低可達22%左右,水玻璃試體沈陷量降低可達27%左右。 |
摘要(英) |
Study of the ability
of soils to resist liquefaction and the settlement after the
liquefaction with adding various cemented materials into sand layer is
the main purpose of this article. This article also examines the
correlation between water permeability and liquefaction in a variety of
cemented samples. These results can be used as a valuable reference for
the future practical applications. The study revealed that the higher
content of cemented materials in sandy soils result in smaller
coefficient permeability κ. Compare the samples without cemented
materials, the coefficient κ decreased 99% for soils with 12% cement
content sample. The coefficient κ decreased 93% for soils with 12%
Sodium silicate content compared with the sample without cemented
materials. This study use the liquefaction energy factor K(t) to
evaluate the ability of soils to resist liquefaction. In the samples
with curing age 28 days, K(t) is about 220 times for samples with 12%
cement content compared with that of content 0%. The K(t) is about 450
times for samples with 12% Sodium silicate content compared with that of
0% sample. The settlements resulting from liquefaction decrease 22% for
samples with 12% cement content and decrease 27% for 12% Sodium silicate
content. In general, result shows that the higher cementation level, the
lesser settlement after liquefaction. |
