深厚抛填黏性土中强夯有效加固深度及加固效果应用研究
摘要:结合合肥某深厚抛填黏性土强夯地基处理项目,介绍了8000 kN·m能级强夯夯击情况,通过静力触探试验、标贯试验、室内土工试验、浅层平板载荷试验研究,分析了抛填厚度8～10 m、含水率19.5%～30.8%、塑性指数17.6～21.8的黏性土强夯前后主要物理力学性质指标的变化,研究了高能级强夯在深厚抛填黏性土中有效加固深度及加固效果。
Abstract:Relying on a deep-filled clay soil foundation treatment project in Hefei,the 8000 kN·m energy level strong slamming situation was introduced.Through the static penetration test,the standard penetration test,the indoor soil test,and the shallow flat plate load test,the changes of main physical and mechanical properties before and after dynamic compaction of the cohesive soil with 8 to 10 m cast,19.5% to 30.8% moisture content,and 17.6 to 21.8 plasticity index were analyzed.The effective reinforcement depth and reinforcement effect of high-energy-grade dynamic compaction in deep throw-in cohesive soil are studied.
