摘要
通过对苏州地区隧道开挖土物理力学性质和颗粒分析,表明进行水泥改良是适宜的。通过对水泥改良土进行击实、承载比和无侧限抗压强度试验,结果表明土性指标得到显著提高,改良后土体可用于路基填筑,节约了资源,并对类似工程有借鉴意义。
Through the analysis of physical and mechanical properties and particle analysis for tunnel excavation soil in Suzhou area,it is proved that it is suitable to improve the soil with cement.Through the compaction,CBR and unconfined compressive strength test of cement improved soil,the results show that the soil index has been significantly improved.The improved soil can be used for subgrade filling,resources are saved,and it is useful for similar projects.
