外用改良剂改善吹填土工程性质的试验研究

Research on Improving Engineering Properties of Dredger Fill with Additive

针对改善吹填土工程性质的方案 ,在吹填土内加入一种化学改良剂 ,通过大量的土工试验 ,希望加快其水分的析出 ,降低含水量 ,增大其渗透性 ,以增加土体的强度 ,从而更好地利用吹填土。通过土工试验得到土体添加改良剂和未添加改良剂的物理力学性质指标。研究结果表明 ,这一方案是可行的。

According to project on improving engineering properties of dredger fill, we add a kind-ofchemistry additive into dredger fill.By a lot of test for geo engineering, we expect oozing out of its water and decreasing of water content.Accordingly, it can enlarge properties of penetration of water and increase its strength and make better use of dredger fill. We get the index of physical mechanics in the soil with additive and without additive through test. In fact, the project is practical.
