چکیده

برای تقویت و تثبیت لایه­های خاک­ریز باید از روش­های تثبیت مناسب استفاده کرد. هدف این پژوهش ارزیابی اثر خاکستر مازاد مقطوعات در بهبود ویژگی­های خاک است. برای این کار، 15 نمونه خاک از شیروانی خاک­ریزی به­صورت تصادفی انتخاب و با توجه به طرح اختلاط سه، شش، نه و 12 درصد وزنی با خاکستر مازاد مقطوعات ترکیب شد. برای بررسی اثر افزودن مواد تثبیت­­کننده بر خاک، آزمایش­های حدود اتربرگ، نسبت باربری کالیفرنیا و رطوبت و هم­چنین اسیدیته، هدایت الکتریکی، فسفر، نیتروژن، ماده آلی، کربن و بر روی نمونه­های خاک تیمار­شده و شاهد انجام شد. مقایسه کلی داده­های تیمارها و شاهد برای صفات اندازه­گیری­شده با استفاده از آزمون آنالیز واریانس یک­طرفه (ANOVA) انجام و میانگین تیمارها با استفاده از آزمون توکی در سطح احتمال پنج درصد مقایسه شدند. نتایج حاصل از آزمایش­ها نشان دادکهافزودن خاکستر مازاد مقطوعات به خاک، حد خمیری و نسبت باربری کالیفرنیا را افزایش و حد روانی و شاخص خمیری را کاهش داده است. نتایج حاصل از آنالیز واریانس یک‌طرفه نشان داد اختلاف میانگین در مقدار رطوبت، اسیدیته و نیتروژن معنی­دار نبود (05/0P>)، این در حالی است که هدایت الکتریکی، فسفر، پتاسیم، ماده آلی و کربن تفاوت­های معنی­داری را نشان دادند.

چکیده [English]

In order to strengthen and stabilize the soil masses in the range of soil till optimum, it should be used appropriate stabilization methods. The purpose of this study was to evaluate the effect of excess ash as an additive to soil and improve soil properties. To do this, 15 soil samples from the forest road fill slope were randomly selected combined with 3, 6, 9 and 12 weight percent logging residual ash. In order to investigate the effect of addition of stabilizing agents on the chemical and mechanical parameters of soil in the studied area, the experiments Atterberg limits, California bearing ratio, moisture as well as acidity, electrical conductivity, phosphorus, nitrogen, organic matter and carbon were carried out on control and treated soil samples. Data were analyzed using one-way ANOVA and Tukey tests were used to compare the averages. The results of the experiment show that the addition of logging residual ash increased plastic limit and California bearing ratio and reduced liquid limit and plasticity index. Also, the results of one-way ANOVA showed that the mean difference in moisture, acidity and nitrogen were not significant (P>5%) while electrical conductivity, phosphorus, potassium, organic matter and carbon showed significant differences.
