相对于传统的静态载荷试验方法，本文对一种称为静态载荷试验的新方法进行了评价。案例历史的审查，提供了一个基础的比较，从静态测量估计的静态容量与传统的负载-挠度测量。当使用Middendorp提出的简单程序进行评估时，在大多数情况下，静态方法预测的载荷-挠度响应与传统静态载荷试验的测量结果相对接近。与本文中概述的传统静载试验的比较表明，在砂土中可以获得极好的一致性，但目前的评估程序可能倾向于高估高达30%的刚性，超固结粘土的能力。
A new method of load testing, called statnamic, is evaluated with respect to conventional methods of static load testing. Case histories are examined that provide a basis for comparison of static capacity as estimated from statnamic measurements with that of conventional load-deflection measurements. When evaluated using the simple procedure proposed by Middendorp, the statnamic method is shown to predict load-deflection response that is relatively close to that measured with conventional static load tests in most cases. Comparisons with conventional static load tests outlined in this paper suggest that excellent agreement can be obtained in sandy soils, but that the current evaluation procedure may tend to overpredict capacity by as much as 30% in stiff, overconsolidated clays.
