摘要

土壤水泥在土木工程界的應用已是相當廣泛，如公路、水壩、機場之鋪面基底層等。土壤水泥是以就地取材的方法來施工，利用現地的土壤，添加適量的水泥與其他添加劑加以拌合，故如何依照現地的土壤，節省水泥用量並訂定出最佳施工配比，製造出符合現地工程需求的土壤水泥是一個值得研究的課題。

本研究主要探討土壤添加水泥及飛灰所製成土壤水泥的力學性質，為了能有效的降低其滲透性，選擇飛灰作為其添加劑，在添加不同配比的水泥及飛灰，由單壓試驗與滲透試驗，探討不同的水泥及飛灰含量，對於土壤水泥抗壓強度及滲透性的影響。

本研究結果指出添加了飛灰的土壤水泥，不僅因為水泥的膠結作用發揮強度，又因飛灰的填充效應，滲透性係數有很明顯的降低，故飛灰添加於土壤水泥中的改善為良好的。

The application in the civil engineering of soil cement has already been quite extensive. for instance highway, dam, pavement of airport,etc.. Soil cement constructs with the method of using in-situ soil, utilize in-situ soil, add suitable amount cement and other additive to mix. How to accord with in-situ soil, save cement consumption and make best construction proportion, is it accord with soil, A subject is worth studying that produce soil cement accord with project requirement.

The main purpose of this study is to study engineering properties of soil cement adding fly ash. For the permeability of reducing that be able to effective, choose the fly ash as their additive, By compress test and permeability test, To study influence of soil cement compression strength and permeability that add different content of cement and fly ash.

This result of study points out that the soil cement add fly ash, not merely Increase strength because cement, permeability coefficient reducing obviously because fly ash. so the improvement that soil cement adding fly ash is good.
