Abstract EN
The relics built with soil are called earthen archaeological sites.
Many silt earthen sites exposed to natural environment get seriously damaged and thus require urgent restoration with suitable materials.
Previously, lime and glutinous rice slurry were used in the construction of earthen sites.
However, lime is usually used in clay, and glutinous rice pulp is difficult to prepare and use on a large scale.
Therefore, in this study, starch ether was selected to replace glutinous rice pulp.
Lime and starch ether were added to silt as single or double additives, respectively, to prepare the corresponding single-mixed and multiple-mixed modified soil samples.
Furthermore, the direct shear test and compression test were carried out and the optimum content was determined.
The strength and durability of optimum modified materials were compared with those of the original site soil.
When the lime content was 9% or the concentration of starch ether solution was 5%, the shear strength and compression resistance ability of single-mixed modified soil were improved significantly.
When lime content was 6% and starch ether solution was 5%, the strength of multiple-mixed modified soil was the best, and the maximum cohesion and internal friction angle were 51.1 and 3.37% higher than those of single-mixed soil, respectively.
The strength and durability of the optimum modified soil were similar to or higher than those of the site soil.
Thus, it is feasible and effective to use lime together with starch ether as restoration material for silty earthen sites.
