摘要
盘锦净水厂岩土工程勘察,通过室内试验与原位测试,对表层软塑粉质黏土层提出准确、合理的物理力学参数。对比分析表明:原位测试能较好反映土的实际状态,得出的承载力及抗剪强度指标较室内试验合理。盘锦地区软土勘察,建议采用标准贯入试验为主,十字板剪切试验、静力触探为辅,多种原位测试应相互对比验证,为类似工程项目建设提供借鉴与参考。
Based on geotechnical investigation of Panjin Water Purification Plant,accurate and reasonable physical and mechanical parameters of soft plastic silty clay layer are proposed through laboratory test and in-situ test.Comparative analysis shows that the in-situ test can better reflect the actual state of soil,and the bearing capacity and shear strength indexes obtained are more reasonable than those obtained in laboratory test.In the soft soil investigation in Panjin area,it is suggested to adopt standard penetration test as the main method,cross plate shear test and static penetration test as the auxiliary method,and various in-situ tests should be compared and verified to provide reference for similar engineering projects.
