| 摘要(中) |
本論文研究的目的在探討土壤材料種類、級配和水泥用量等因素對土壤水泥抗壓強度等工程性質之影響。期能獲得相關研究成果，以提供執行中之湖山水庫計畫，在其附屬工程方面之應用，或者作為日後其他水庫工程計畫案，在大壩坡面保護工之拋石材料不易取得時，當作替代方案之規劃設計參考。影響土壤水泥材料工程性質之主要因素包括：(1)土壤原料、膠結劑的種類和拌合比例及含水量；(2)夯實程度；(3)拌合的均勻程度；(4)養護狀況；及(5)齡期程度。 本論文主要是採用「湖山水庫工程計畫土壤水泥之性質試驗及適用性探討研究」計畫案之試驗資料，藉由土壤水泥之相關試驗結果，針對土壤材料種類、土壤級配、粒徑大小、細粒料含量、齡期和水泥用量等因素，對土壤水泥抗壓強度之影響進行分析與研究，並與相關參考文獻資料做對照驗證。 本論文研究發現：(1)對於不同的土壤材料及級配，在水泥含量與最大乾密度及最佳含水量之關係，會有明顯的差異，細粒料含量低之材料，其最大乾密度明顯會隨水泥含量增加而增加；但細粒料含量高之材料則不明顯。(2)在相同之水泥含量下，土壤材料之平均粒徑（D50）及級配均勻係數（Cu）與最大乾密度均呈正比關係，而最佳含水量則呈反比關係。(3)又土壤水泥之抗壓強度會隨著水泥含量及齡期的增加而增加；而抗壓強度亦會隨著最大乾密度、平均粒徑（D50）及均勻係數（Cu）的增大而增加。 由試驗結果及根據美國墾務局之規範，本研究分析結果得知，湖山水庫工程若擬採用土壤水泥，適合之土壤材料為3RS1土樣或混合料（MIX1、MIX2），且水泥用量為11%以上。但就經濟考量，則建議選用3RS1，水泥用量11%為最佳。又土壤水泥適用之材料粒徑多偏粗顆粒，研判材料粒徑越大者，應越適用於土壤水泥。本研究所得之「土壤水泥適用材料之建議粒徑分佈曲線上、下限範圍」，應可提供國內工程界在採用土壤水泥時，土料選用之參考。 | |||
| 摘要(英) | The purpose of this
thesis is to investigate the effect of soil types, gradation and cement
content etc. on the structural properties of soil-cement mixtures and to
expect to obtain important conclusions for soil-cement application not
only to the attached construction of on-going project of [ Hu-san Dam
construction] but to other future soil-cement application where
soil-cement, as an alternative to rock riprap for slope protection, is
not locally available.The properties of soil-cement are influenced by
several factors, including (a) type and proportion of soil, cementitious
materials, and water content, (b) compaction,(c) uniformity of
mixing,(d)curing conditions and (e)age of the compacted mixture. The further continuing investigation in this thesis are mainly based on the test data presented in “ Research on the properties and the feasibility of soil-cement for Hu-san Dam construction”. Eight research soils of different gradation were included and are all non-plastic soils. The research soils are classified to be 2 types according to the particle size distribution where Type 1 soils had the finer gradation and Type 2 soils had the coarser gradation.Cement additions ranged from 5% to 13% by weight of soil. The particle size distribution, gradation and physical properties of different soils are presented. The investigation results are verified in comparison with cited references. Based on the experimental results, the findings are presented as follows: (1)The effect of soil type and gradation on the relationship between cement content and maximum dry density and on the relationship between cement content and optimum moisture content had remarkable difference. The maximum dry density increased with an increase in cement content for lower contents of fine-grained soils. However, no significant variation was noticed for higher contents of fine-grained soils. (2) For a given cement content, the average grain size （D50）and uniformity coefficienteffect of soil gradation（Cu）had the relationship of direct proportion with maximum dry density of soil-cement mixtures. However, D50 and Cu had the relationship of inverse proportion with optimum moisture content. (3) The compressive strength of all soil-cement mixtures increased with an increase in cement content and with an increase in moist curing period. The compressive strength of all soil-cement mixtures increased with an increase in maximum dry density , the average grain size（D50）and uniformity coefficienteffect（Cu）. Based on USSR criteria and in the analysis of the experimental results, a minimum of 11% of cement contents for soil 3RS1, MIX1and MIX2. are suitable for soil-cement application on the project of [Hu-san Dam construction] in the near future. But in view of cost-saving, soil 3RS1 with a minimum of 11% of cement contents are recommended. In addition, the coarser grain soils are more applicable than finer grain soils to soil-cement construction. “Grain size distribution of the different soils suitable for soil-cement applications presented in this thesis are recommended to refer to. | |||
