摘要： 钢钎静探是近期出现的一种便携式新型勘探设备，具有地层划分及直接测试贯入地基反力等勘探功能，为验证地基贯入反力与静力触探比贯入阻力PS之间的转换关系，以无为某公路项目为依托，将钢钎静探引入到路基勘察中，同时开展钢钎静探与静力触探、麻花钻及室内试验成果对比试验研究，对钢钎静探与单桥静力触探试验PS～h曲线、地层划分及确定地基承载力方面进行对比分析，研究钢钎静探试验结果的准确性及可靠性，并为其进一步推广应用积累经验。

Abstract: The static steel chisel sounding is a new portable subsurface exploration device. This device has the functions of classifying the soil stratigraphy and measure the subgrade reaction. This paper presents a case history of comparison between the static steel chisel sounding (SSCS) penetration and penetration resistance obtained by cone penetration test (CPT) and their relationships in a highway project in Wuwei City. The subsurface investigation results obtained by SSCS, CPT, special disturbed soil sampler and laboratory test are evaluated; the tip resistance with depth curves and stratigraphy obtained by SSCS and CPT are compared; the reliability of the SSCS is discussed in this paper. 

Key words: static steel chisel sounding, subsurface investigation, in-situ test, foundation bearing capacity evaluation
