摘要

摘要 含水量变化时体积变化大的土壤被认为是可塌陷土壤。粘性土是可塌陷土壤的主要类型之一,可在干旱和半干旱地区找到。本研究通过实验研究了初始含水量对天然吉普赛土和添加 5%水泥处理过的吉普赛土的可塌陷性的影响。土壤在不同的初始含水量(即 5%、10%、15% 和 20%)下进行测试。两种土壤的石膏含量分别为 28.43 % 和 43.62 %,分别命名为土壤 1 和土壤 2。土壤取自伊拉克萨拉丁省提克里特市。结果表明,初始含水量对塌陷潜力有显著影响。当初始含水量为 20% 时,天然土壤的塌陷减少率高达 70%。此外,天然土壤的塌陷减少量大于不同初始含水量的处理过的土壤。由此可以得出结论,增加初始含水量可以减少塌方这一主要问题。

Effect of Initial Water Content on the Collapsibility of Natural and Cement-Treated Gypseous Soils
Abstract Soils that exhibit high volume change when its water content is changed are considered collapsible soils. Gypseous soils are one of the main types of collapsible soils which can be found in arid and semiarid areas. In this study, the effect of initial water content on the collapsibility properties of natural and treated gypseous soils with 5% of cement is experimentally investigated. The soils tested at different initial moisture content i.e. 5 %, 10 %, 15 %, 20 %. Two types of soil were used with different gypsum content 28.43 % and 43.62 % named soil 1 and soil 2 respectively. The soils were taken from Tikrit city in Saladin governorate – Iraq. The results show that the initial water content has significant effect on the collapse potential. The reduction in collapse for natural soils reaches up to 70 % when the initial water content was 20 %. Furthermore, the reduction in collapse for natural soils was greater than that for treated soils with different initial water content. It can be concluded that increasing initial water content can reduce the sudden collapse which is a major problem.
