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P_(S)~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。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.
