1.It is found that the key to ensure the safety of the rock-anchored beam under blasting vibration is to prevent the cracking of the bonding interface between the beam and the vertical rock wall,and to control the horizontal peak particle velocity,which is vertical to the side wall.利用动力有限元数值模拟,研究爆破震动荷载作用下岩锚梁的动态响应特性,研究结果表明爆破震动作用下保证岩锚梁的安全关键在于防止岩锚梁与岩台黏结面被拉裂,应严格控制岩锚梁水平向质点峰值振动速度。
2.Basen on the criteria of the peak particle velocity(PPV) for blast-induced damage,the design approach for excavation blasting near contour of rock slope is discussed.基于岩石爆破损伤影响范围控制的质点峰值振动速度判据,就临近岩石边坡开挖轮廓面的爆破开挖设计方法进行了探讨。

第二峰值法试验分子式:CAS号:性质:一种检验不锈钢晶间腐蚀倾向的快速的电化学方法。对敏化的不锈钢试样在1mol/L H2SO4中测定阳极极化曲线,曲线上在比活化钝化峰更正的电位下出现第二峰,峰的高度可以表示晶间腐蚀倾向的大小。也可在第二峰值电位下保持2h,然后进行弯曲试验,根据试样的裂纹判断晶间腐蚀倾向。
