苏联白俄罗斯综合技术学院《地基基础和工程地质》教研室等单位,为了判明桩的形式影响以及它们在设计和施工方面的实践效果,研究了圆柱形的、正棱柱形的、正方角锥形的、三角锥形和矩形角锥形等打入式桩。试验判明:方形桩的单位承载力主要依赖于桩的横截面尺寸大小,在截面大小变化的同时,桩的单位承载力可以提高2.8倍(对于5米长的桩)至4.3倍(对于15米长的桩)。桩的单位承载能力p取决于桩的横截面的形 In order to determine the form effects of piles and their practical effects in design and construction, the Institute of Foundation and Engineering Geology of the Belarusian Institute of Integrated Technology of the Soviet Union studied cylindrical, prismatic, square pyramidal, Taper piles such as triangular cones and rectangular pyramids. The tests showed that the unit bearing capacity of a square pile mainly depends on the size of the cross-section of the pile. While the size of the section changes, the unit bearing capacity of the pile can be increased by 2.8 times (for 5 meters long piles) to 4.3 times (for 15 meters) Long pile). The bearing capacity p of the pile depends on the shape of the cross section of the pile
