摘要
针对气泡含量对气泡轻质土抗剪强度及冻融循环对其抗压强度和吸水率的影响问题,通过三轴试验和抗压强度试验,对气泡轻质土的力学特性进行了研究,得出以下结论:随着气泡含量的减小,气泡轻质土的破坏峰值逐渐增大;当混合料比例一定时,冻融循环对气泡轻质土吸水率的影响较弱,气泡含量对吸水率影响较小;气泡轻质土粘聚力随着气泡含量的增加而减小,内摩擦角则呈现先增大后减小的趋势。
In order to study the influence of foam content onshear strength, compressive strength and water absorption of foamed cement banking, the mechanical properties of foamed cement banking were studied. The following conclusions were drawn based on a large number of triaxial tests and compressive strength tests.the peak of destruction to foamed cement banking mounts when the foam content drops; when the proportion of mixture is fixed, the effect of freeze-thaw cycles and foam content on the water absorption is weak; with the increase of foam content, the cohesion diminishes, while the inner friction increases at first and then decreases.
