摘要
基于孔穴扩张理论,采用Mohr-Coulomb屈服准则,针对饱和软土及其特点进行简化分析,在此条件下获得问题的应力解,从而建立双桥静力触探侧摩阻力fs的实用理论计算关系式,并加以应用对比分析,结果表明了所得关系式的科学合理性,为双桥静力触探的进一步推广应用提供了依据。
Based on the cavity expansion theory,the stress solution and CPT(Cone Penetration Test) lateral friction coefficient formula are obtained in saturated soft soil;results between the formula and situ-test data show that the formula is of rationality,which is promoted the further popularization and application of CPT.
