本文利用在一根直径为1.2m、埋深为8.5m的管桩上进行的倾复试验,比较了两种不同的设计方法所获得的结果。通常,利用压力计在现场进行土壤的研究试验是一种非常适合这类基础设计的有效方法。线性特性模型虽不能保证充分地预测土壤中产生的运动和应力,但它却能正确地得到一些有关角位移和弯矩的数据。非线性塑变特性模型似乎更适用于这类基础的设计,但它要求在确定两个附加参数的基础上建立一个比较复杂的设计规则。
This paper makes use of a plunge test on a pipe pile with a diameter of 1.2m and a depth of 8.5m to compare the results obtained by two different design methods. In general, conducting research tests on soil in situ using pressure gauges is an effective method that is well-suited for this type of foundation design. Although the linear characteristic model can’t guarantee to fully predict the motion and stress generated in the soil, it can correctly obtain some data about angular displacement and bending moment. The nonlinear plastic properties model seems to be more applicable to this type of basic design, but it requires the establishment of a more complex design rule based on the determination of two additional parameters.
