基于SH加固材料的土遗址夯土试样室内滴渗试验研究
Laboratory tests on rammed earth samples of earthen sites instilled by reinforcement material SH
摘要
Abstract
The earthen sites in the northwest arid area of China are suffering from surface weathering heavily. Currently, the main way to solve the difficulty depends on the researches on anti-weathering materials and their engineering reinforcement and repair. However, the researches on anti-weathering materials cannot satisfy the practical engineering at present. The penetration diameter and the distribution and changing characteristics of penetration rate on the surface of the rammed samples are studied when they are instilled by different concentrations of SH as well as the change of wave velocity and the disintegration on the wall after penetration. The test results indicate that the optimal grouting capacity of a single hole is 30~40 mL, the instilling penetration at this time is about 300 min, and the final surface penetration radius is 3~4 cm. After instilled by SH, the wave velocity and the anti-disintegration of the samples obviously increase, especially for the 1.0% SH.关键词
