水下流态固化土强度与流动性能试验研究
Experimental study on strength and flow properties of underwater flow-solidified soil
摘要
Abstract
In order to enhance research on the underwater construction performance and unconfined compressive strength of fluid solidified soil,water reducing agent,cement,and flocculant were added to soil with different initial water contents.The effects of water content,water reducing agent content,cement content,and flocculant content on fluidity,anti-dispersion,and mechanical properties of fluid solidified soil slurry were studied.Results show that cement alone cannot significantly adjust fluidity and anti-dispersion of fluid solidified soil slurry.Increased flocculant and cement content improved anti-dispersion of solidified soil slurry and mechanical properties of solidified soil,while inhibiting fluidity of solidified soil slurry.Increased water reducing agent and water content promoted fluidity of solidified soil slurry,but inhibited anti-dispersion and mechanical properties of solidified soil slurry.关键词
