| 摘 要： | 基于断裂力学原理,从简单ANSYS断裂模型出发,计算石拱桥砌石裂缝在不同灌浆压力作用下的缝端应力强度因子,再依据裂缝扩展准则工程判据,分析整段灌浆的允许灌浆压力以及不同分段灌浆长度下的允许灌浆压力,为压力灌浆修补裂缝技术提供理论支撑。 |
| 关 键 词： | 断裂力学 裂缝 应力强度因子 允许灌浆压力 |

| Abstract: | Based on the fracture mechanics,the crack stress intensity factors of the stone arch bridge under different grouting pressure are calculated,starting from a simple ANSYS fracture model.And then through the criterion of crack propagation,the allowable grouting pressure of entire grouting and the allowable grouting pressure with different segments grouting length are analyzed,which provides theoretical support for grouting pressure repair cracks. |
| Keywords: | fracture mechanics crack stress intensity factor allowable grouting pressure |
