本文仅就大直径桩在重工业厂房中的应用作了实际试验研究,试验用的是静荷载法,对大直径单桩在轴向和横向荷载作用下进行了试验.试验结果证明,大直径桩的承载能力较高、质量较好、造价低,并能避勉施工中的公害.因此,大直径桩在重工业厂房中的应用,技术可行,经济合理. In this paper, the practical test of large-diameter piles used in heavy industrial workshops was made. The static load method was used in the tests. The tests were carried out on large-diameter single piles under axial and lateral loads. The test results proved that the large-diameter piles The high carrying capacity, good quality, low cost, and can avoid the pollution during construction. Therefore, the application of large diameter piles in the heavy industrial plant, technically feasible, economical and reasonable.
