【摘要】 以节约耗材、施工快速、质量可控等为目标，结合陆上风电梁板式基础结构特点，提出一种新型单块双肋梁装配式基础。目前对装配式梁板基础结构受力特性的研究较少，该文通过建立基础整体有限元模型及开展室内模型试验，研究预制装配式梁板基础受V（竖向荷载）-H（水平荷载）-M（弯矩荷载）复合荷载下的结构受力特性，并重点分析基础肋梁、底板、台柱等的承载及破坏模式。研究表明，新型单块双肋梁装配式基础结构具有良好的承载及结构力学性能，安全储备可达设计值的1.44倍；基础整体稳定性良好，各项指标满足现有规范设计要求；同时，台柱-肋梁交接处为此类型基础结构承载及荷载传递的关键部位，设计及施工时应重点关注。更多还原

【Abstract】 With the goal of saving materials, ensuring rapid construction, and ensuring controllable quality, a new type of single double-ribbed prefabricated assembly raft foundation is proposed by considering the structural characteristics of raft foundations.Currently, there is limited research on the mechanical characteristics of prefabricated raft foundation structures. This study establishes a comprehensive finite element model of the foundation and conducts model experiments to investigate the structural load-bearing characteristics of prefabricated raft foundations under V(vertical)-H(horizontal)-M(moment) composite load. It specifically focuses on analyzing the load-bearing capacity and failure modes of foundation rib beams, baseplate, and pillar supports. The results show that the new single double-ribbed prefabricated raft foundation structure has good load-bearing and structural mechanical properties, and the safety reserve can reach 1.44 times the design value. The overall stability of the foundation is good, and all indicators meet the design requirements of existing specifications. The junction between the column and the rib beam is a key part of the bearing and load transfer of this type of foundation structure, which should be paid attention to during the design and construction.更多还原
