摘　　要：静探是岩土工程勘察最常用的一种手段,其测试结果几乎与土的各种物理力学指标建立了关系。但影响测试结果精度的因素很多,而且影响程度也各不相同。分析了实际存在的贯入速率不达标的情况对淤泥质土测试结果的影响程度,并通过现场原位试验验证,以期使静探测试结果在工程勘察中得到更好的应用。The static sounding is the most common means in the geotechnical engineering survey.Its test result is almost related to various physical mechanics indexes.However,there are many factors to affect the accuracy of test result,and the influence extents are different.The article analyzes the influence extent of the practically existing penetration rate not up to standard on the test result of mucky soil.The validation of the field test expects the static sounding test result to be better applied in the engineering survey.

关 键 词：静力触探 贯入速率 贯入阻力
