| 摘 要： | 基于流形方法的有限覆盖技术，确定流形元覆盖系统下锚杆的位移函数，由此建立全长粘结锚杆的数值流形方法模型，定义了锚杆流形单元，并推导了锚杆流形单元的数值计算格式。该模型符合全粘结的物理意义，是一种局部解析的锚杆数值方法，具有较高的精度。同时锚杆与数学覆盖相对独立，只要求锚杆完全处于数学网格的覆盖之中，对其相对位置没有要求，所以一般网格可以适应锚杆的复杂布置。该模型可以应用于岩土锚杆模拟及钢筋与混凝土共同作用分析等问题。

| Abstract: | Based on the finite cover techniques of manifold method, the displacement function of bolt was determined according to the cover system of manifold element; and the numerical manifold model of fully-grouted bolt was established; and the concept of bolt manifold element as well as its numerical calculation form were obtained. This model meets the physical meaning of fully-grouted condition; it is a numerical method of bolt with feature of partial analysis and better calculation accuracy. At the same time, bolt and mathematics cover are relatively independent, only the bolt is required to be in mathematics grid, while no have strict requirement of their relative location has to be met, so general grid can meet complex configuration of bolt. This model can be used in simulating geotechnical bolt and analyzing the interaction of reinforcing bar and concrete. |
