The study of analyzing the mechanical of aeolian sandy soil using straw based on experiment 应用吸管法进行风沙土机械组成分析的实验研究
The article analyses nature of lime , manganese iron , aeolian sandy soil , cement , and material requirement of roadbed 论文分析了石灰、锰铁废渣、风积砂土、水泥的性质,以及阐述了路面基层对材料的要求。
The slity soil has the greatest frost heave strength in all of soil and the aerolian sandy soil belongs to it , so it is necessary to the study on frost heave mechanics of aeolian sandy soil and measure of prevent frost heave in railway construction 风积砂土属于粉质土,而粉质土的冻胀强度是最大的,因而对风积砂土的冻胀性及其对铁路危害的研究是非常有必要的。
Under applying k 200mg / kg , k fixation capacity of four soils strengthened with drying and wetting cycle and temperature increasing , so , the availability weakened . in general , capacities of fixing potassium of soils in turns were : heir lu soil > lou soil > loessial soil > aeolian sandy soil 在施钾量为200mg kg的情况下,干湿交替对四种土壤钾的有效性影响程度由大到小依次为:土娄土、黑垆土、黄绵土、风沙土。
