我国西南山区是地震高发区,强震作用下易引发滚石灾害,是影响高坝附属建筑物安全的重要隐患。为了探讨滚石冲击作用下进水塔轨道梁损伤机理,建立了滚石冲击进水塔数值模型并利用滚石冲击试验验证了数值模拟方法的可靠性,对比分析了滚石冲击角度、直径以及速度对轨道梁破坏模式的影响。结果表明:轨道梁受滚石冲击后,破坏形式表现为冲击点被压碎并形成拉裂缝、两端产生剪裂缝、跨中形成弯曲裂缝以及贯穿至支座处的斜剪裂缝;梁内钢筋产生弯曲变形,呈现明显冲切特征。不同冲击角度下滚石冲击作用结束后对轨道梁造成二次破坏的可能性较小;当滚石入射角度小于45°时,入射角越大,反射角越小,滚石入射角度大于45°时,规律相反;冲击角度为60°时,轨道梁损伤最严重。轨道梁的损伤程度与滚石直径、滚石冲击速度呈正相关,当直径为1.0m的滚石的冲击能量大于5749J时,轨道梁会被破坏,影响正常运作。
The mountainous areas in southwestern China are high-risk areas for earthquakes
and under strong earthquake action
they are prone to rock rolling disasters
which is an important hidden danger affecting the safety of the ancillary buildings of high dams. A numerical model is established to investigate the damage mechanism of the track beam of the intake tower under rockfall impact
and the reliability of this simulation method is verified through impact testing. What’s more
the effects of rockfall impact angle
diameter
and velocity on the damage mode of the track beam were compared and analyzed. The results show that after the track beam is impacted by rockfall
the damage form is characterized by crushing at the impact point
forming tensile cracks
generating shear cracks at both ends
forming bending cracks in the midspan
and forming oblique shear cracks penetrating to the support; the reinforcement in the beam undergoes bending deformation
showing obvious punching characteristics. The likelihood of secondary damage to the track beam following impact from a rolling stone at various angles is minimal. When the incident angle of rockfall is less than 45°
the larger the incident angle
the smaller the reflection angle
and when the incident angle is greater than 45°
the opposite rule holds. When the impact angle is 60°
the damage to the track beam is most significant. The degree of damage to the track beam is positively correlated with the diameter and impact velocity of rockfall. When the impact energy of a 1.0m rockfall is greater than 5749J
the track beam will be damaged and fail
affecting the normal operation.
