一、试验目的进行单桩垂直静荷载试验有以下四个方面的意义: 1.为设计提供合理的单桩承载能力,这属于检验性质的垂直承载能力的试验。作为基础桩,其材料要达到规定的材质强度,其承载能力和变形特性要满足设计要求。本讲座所讨论的垂直承载力,不是由桩材料的强度与土的强度决定的,而是由桩与土的相互作用决定的。
First, the purpose of the test The vertical static load test of a single pile has the following four aspects: 1. To provide a reasonable design of the bearing capacity of a single pile, which is the test of vertical load carrying capacity test. As the foundation pile, its material must reach the specified material strength, and its carrying capacity and deformation characteristics must meet the design requirements. The vertical bearing capacity discussed in this lecture is not determined by the strength of the pile material and the strength of the soil, but is determined by the interaction of the pile and the soil.
