SH灰土和糯米浆灰土材料物理力学性质对比
|
摘要
通过研究SH灰土和糯米浆灰土两种加固材料保护土遗址.通过对比分析灰土保水性、吸水性和收缩性对灰土物理性质,无侧限抗压强度、纵波波速、青砖-灰土黏结强度和抗剪强度对灰土力学性质,研究干湿冻融循环对灰土物理力学性质的影响,针对拜寺口塔林62座塔基修复选择最适灰土.
Two reinforcement materials, SH mortar and sticky-rice mortar, were studied to protect earthen ruins. The physical properties of lime-soils including water-retaining property,absorbency and contractility were analyzed and compared. Compared were the mechanical properties of lime-soils such as unconfined compressive strength, longitudinal wave velocity, boning strength of blue-brick and lime-soils and shear strength. Dry-wet and freezing-thawing cycle has an impact on the physical and mechanical properties of the lime-soils. The best mortar was chosen for repairing 62 column bases in Baisikou pagoda forest.
