摘　　要：在某工程现场微型贯入试验成果的基础上,将数值模拟方法应用到微型贯入试验中,并将数值模拟结果与现场微型贯入试验和室内试验的结果进行对比分析,从含水率、湿重度、微型贯入仪与土体间摩擦及其对贯入阻力的影响出发,验证现场微型贯入试验对淤泥质粘土试样的合理性,可供现场试验参考。On the base of micro-penetration test result in one project, we apply numerical simulation method in the micro-penetration test. The numerical simulation result, field micro-penetration test and indoor test results are compared and analyzed. From the perspectives of water content, humid weight, the friction of micropenetration instrument against soil body and its impact on the penetration resistance, we verify the reasonableness for the field micro-penetration test of silty clay sample, which will provide references for the field test.
