摘　　要：文章针对苏州市某场地环境与工程地质条件进行勘察,通过原位测试技术对软土地基进行评价。研究发现,场地主要由填土、冲洪积层和泥质砂岩构成,地下水类型包括孔隙水和基岩裂隙水。采用标准贯入试验、十字板剪切试验和静力触探试验,评估了土层的承载力和力学特性。结果表明,原位测试技术能有效指导软土地基处理,确保工程安全,为类似地质条件下的工程建设提供了重要参考。This paper investigates the environment and engineering geological conditions of a site in Suzhou City,and evaluates the soft soil foundation by in-situ testing technology.It is found that the site is mainly composed offilling soil,alluvial layer and argillaceous sandstone,and the groundwater types include pore water and bedrock fissure water.The bearing capacity and mechanical properties of the soil layer are evaluated by standard penetration test,vane shear test and static cone penetration test.The results show that the in-situ testing technology can effectively guide the treatment of soft soil foundation and ensure the safety of the engineering,which provides an important reference for the engineering construction under similar geological conditions.
