Rolling construction simulation method for steel bridge deck pavement layer
The invention discloses a rolling construction simulation method for a steel bridge deck pavement layer. The method comprises steps of adopting three-dimensional modeling software to draw a typical coarse aggregate particle three-dimensional model according to actual morphological characteristics of coarse aggregate particles, and establishing a pavement layer model according to the typical coarse aggregate particle three-dimensional model; establishing a steel bridge deck model with a welding seam by using FLAC3D software; coupling the pavement layer model and the steel bridge deck model; loading in a conveyor belt type load simulation mode, and simulating rolling construction of a steel bridge deck pavement layer; and calculating the compaction degree after rolling by adopting the contact number of a single particle parallel bonding model. According to the invention, the real morphology of coarse aggregate particles and the combined structure of the pavement layer and the steel bridge deck can be simulated more accurately and truly; construction quality influence factors such as welding seams, a rolling process and caking materials are considered, and complex working conditions in the rolling construction process of the steel bridge deck pavement layer can be effectively simulated. The influence of the factors on the compaction effect of the pavement layer can be quantitatively analyzed through a contact number method of the compaction degree, the practicability is high, and calculation is simpler and more convenient.
本发明公开了一种钢桥面铺装层碾压施工模拟方法，采用三维建模软件参照粗集料颗粒实际的形貌特征绘制典型粗集料颗粒三维模型并以此建立铺装层模型；使用FLAC3D软件建立带焊缝的钢桥面板模型；对铺装层模型和钢桥面板模型进行耦合；采用传送带式荷载模拟方式进行加载，模拟钢桥面铺装层碾压施工；采用单个颗粒平行粘结模型接触个数计算碾压完成后的压实度。本发明能够更加准确真实地模拟粗集料颗粒的真实形貌以及铺装层和钢桥面板的组合结构；考虑了焊缝、碾压工艺、结团料等施工质量影响因素，可有效模拟钢桥面铺装层碾压施工过程中的复杂工况；通过压实度的接触数法能够定量分析上述因素对铺装层压实效果的影响，实用性强，计算更加简便。
