摘　　要：结合位于白俄罗斯共和国首都明斯克市内的援白俄罗斯国家足球体育场项目,研究基于长螺旋锚桩平台反力装置加载系统的基桩静载试验。为确保试验研究数据准确,基于地质钻探、文献调研、归纳统计等方法,系统查明了项目所在场地岩土地层地质特征,采用单桩竖向抗压静载试验,得到设计最终采用的单桩承载力并验证施工工艺的可行性,并进行破坏性试验,以确定桩基最终承载力,为类似工程单桩静载试验提供借鉴。Combined with the project of the Belarusian National Football Stadium located in Minsk,the capital of the Republic of Belarus,the static load test of foundation pile based on the loading system of the reaction device of the long screw anchor pile platform was studied.In order to ensure the accuracy of the experimental research data,based on geological drilling,literature research,inductive statistics and other methods,the geological characteristics of the rock and soil layer of the project site were systematically identified,and the vertical compressive static load test of the monopile was used to obtain the final bearing force of the design and verify the feasibility of the construction process,and destructive tests were carried out to determine the final bearing capacity of the pile foundation,which provided useful reference for the static load test of monopile in similar projects.
