摘要： 山东西南部地区的软粘土地层具有强度低、压缩性高的特性。当其作为建（构）筑物的地基持力层时，需准确评价其强度及变形特性。针对山东西南部地区高压输电线路建设过程中遇到的软粘土，根据土的物理力学性质指标，通过轻型圆锥动力触探试验、静力触探试验、螺旋板载荷试验等多种方法对比分析，确定了山东西南部地区淤泥质粉质粘土的承载力特征值，并将其应用于线路工程设计。取得了明显的经济效益，对以后的工程建设具有一定的借鉴意义。

Abstract: The soft cohesive soil in Southwest Shandong Province has characteristics of low strength and high compressibility. It is critically important to accurately evaluate its strength and deformation properties for the engineered structures and facilities. This paper presents a soft soil bearing capacity and shear strength evaluation case history of a high voltage power transmission line project over Shandong Southwest soft cohesive soil areas. Different testing and evaluation method were used in the investigation and the appropriate bearing capacity values were recommended.
