中文摘要：
填充高强灌浆材料的连接段广泛应用在海上风电场单桩支撑结构上，但是该类结构往往会发生一些无法预测的灾变行为。如过渡段钢管与灌浆材料之间垂向滑移甚至水平张开。引起该现象的主要原因是灌浆连接段的设计几何尺寸以及材料强度并不符合当前海洋工程规范的适用范围，对灌浆连接段的力学行为理解不充分。文章采用有限元软件ANSYS分析了无剪力键单桩结构灌浆连接段组合结构的相互作用行为，灌浆材料与钢管之间的作用采用非线性接触模型，采用弹塑性和断裂力学模型模拟灌浆材料的非线性行为，最终给出合适的高强灌浆材料连接模拟方法，并分析其性能及失效机制。
英文摘要：
Grout joints with high performance grout fillings have been widely applied on a number of offshore wind farms. But there are examples of unforeseen disaster behavior. For instance, slip surfaces and even gaps have been observed. The main reason is dimensions and material strength of these grout joints deviate from current offshore design standards. Furthermore, the structural behavior of the grout joints is not fully understood. In this paper, ANSYS finite element analysis have been carried out to un- derstand the load carrying behavior of monopile grout joints. The analysis model applies a contact for- mulation describing the interface between the grout and the steel tubular and a non-linear constitutive model for the grout. The applicability of elastic-plastic and crack models have been investigated to find suitable model that describes the non-linear behavior of grout material. The major objective provides a suitable modeling approach and, to the extent possible, gives a structural performance analysis and the failure mechanisms of grout joints with high-performance concrete.
