选择基础型式,在经济上和技术上都是重要的。基础设计需要作土的试验,以便得到土性能的数据。在设计非粘性土中的桩基时,有必要了解土的变形性能。旁压仪是适于确定土的应力——应变关系的仪器。采用得到的土的应力——应变关系发展了基础设计中应用的理论和计算方法。 Choosing the basic pattern is both economically and technically important. The basic design needs to be tested for soil in order to obtain data on soil properties. When designing pile foundations in non-cohesive soils, it is necessary to understand the deformation properties of the soil. The pressure gauge is an instrument suitable for determining the stress-strain relationship of soil. Using the obtained soil stress-strain relationship, the theory and calculation methods applied in the basic design were developed.
