RESEARCH ON THE INFLUENCE OF EMBEDMENT ON THE PENETRATION RESISTANCE OF T-BAR TEST

  • 摘要: 假定软土强度服从Tresca曲服准则,采用数值模拟方法,研究了探头贯入深度对贯入阻力的影响。研究发现,对于轴长比为0.5的椭圆形、矩形和菱形截面探头,当探头中心埋置深度达到4~6倍探头宽度时,贯入阻力趋于定值,探头埋置深度对于工程实践测试结果的影响可以忽略。对于椭圆形和菱形截面探头,以及光滑表面矩形探头,该值与无限软黏土空间理论分析结果一致。对于粗糙表面矩形探头,该值大于无限软黏土空间理论分析结果,粗糙表面矩形探头贯入阻力解析解为近似解。矩形截面探头测试结果需进行适当修正。
