摘要
瞬态动测法试桩有参数动测法、反射波法、机械阻抗法及共振法等等方法。动测试桩分桩身质量检测和单桩承载力测定两部分,前者基于波在介质分界面的反射原理,由反射类型判断桩身缺陷形式;后者则根据线性振动的理论,由经验公式估算。
The piling transient dynamic measurements include parameter transientmeasurement, reflected wave method, mechanical impedance method andresonance method, etc. The measurements include the pile quality test andthe bearing capacity of individual pile. The former based on the reflectionprinciple of the interface between two mediums, determines the defect typesof pile and the later based on the linear vibration principle is estimatedby experience.
