| Summary: | 碩士 === 國立高雄應用科技大學 === 土木工程與防災科技研究所 === 104 === In this study, the layered soil, interbedded from 2KW solar induced osmotic assess the amount of the settlement by the soil using Cianjin District, Kaohsiung City and Pingtung fangliao sand clay this test, the soil is divided into four by the electro-osmosis on to the next as clay, sand, clay, sand and sand, clay, sand, clay soil with two slots compared with each other electro-osmosis after its vertical subsidence and intensity.
The study that saturated sand, clay interbedded soil after 2KW solar penetration induced improvement, improvement of electro-osmosis clay layer vertical blocks within the settlement than the sand layer is about twice as large (1.96-fold), and closer to the negative electrode at the major changes in soil subsidence. Improved soil infiltration complete electrical current solar power is zero, the end time of about one week time point changes in the larger settlement located 2 to 5 days, the electro-osmosis and found that the maximum amount of electro-osmosis subsidence clay layer and sand layer occurs in the next sand on clay, but clay electroosmotic low intensity strength than sand, clay and sand but electroosmotic shear strength was 1.5 to 2 times improved electro-osmotic effect before the good.
The results can be judged when the saturated sand interbedded clay, sand particles, although it contains fine # 200 mesh or less of the soil, but after electroosmosis improved settlement small change, but also because of the clay positive and negative electrode rod than the metal ion adsorption large, and because of the exclusion of moisture so that subsidence becomes large, sand, clay interbedded after settlement amount due to electro-osmosis unevenly distributed, easy to make a difference building subsidence phenomenon occurs. This article imitate one-dimensional theory and compacted clay and sand have done one-dimensional electric electricity permeability index permeability test of trying to calculate the one-dimensional theory of electro-osmosis settlement amount, compare actual settlement amount was the maximum error clay 97.92 %, a minimum of -7.58%, an average of 38.61% of all the error of sand up to 97.22%, the minimum -5.31%, an average of 77.02 percent of all; after considering the electro-osmosis electrode rod corrosion efficiency of different depths mean that all clay error rate dropped to -2.58%, the average error rate is reduced to sand the entire 60.64%, confirming the depth of corrosion considerations different electrode rod efficiency can increase the integrity of the electro-osmotic theory, and its error estimate will be fine.
