摘要
本研究通过数值计算和室内实验仿真的方式开展了对常规岩土力学试验主应力组成分析与疲劳荷载的研究。进行了常规岩土力学试验的仿真,并得出了主应力分布特点。通过建立疲劳仿真计算模型,对试件进行疲劳仿真验证,针对四组不同算例对试件的疲劳荷载进行模拟分析。通过研究得出不同主应力组合对试件的疲劳荷载有着一定影响。
In this paper,the main stress composition analysis and fatigue load research of conventional rock Soil mechanics test are carried out by means of numerical calculation and indoor experimental simulation.The simulation of conventional rock Soil mechanics test is carried out,and the distribution characteristics of principal stress are obtained.By establishing a fatigue simulation calculation model,the fatigue simulation verification of the specimens was carried out,and the fatigue load of the specimens was simulated and analyzed for four different sets of calculation examples.Through research,it has been found that different combinations of principal stresses have a certain impact on the fatigue load of the specimen.
