【摘要】

：

为了控制石灰石生产加工过程中岩粉的产生及分析其成因,利用邦德功指数和研磨性分析了石灰岩的主要特性,结合灰岩粉的主要来源,提出了针对性的岩粉控制措施,并通过灰岩矿爆破试验进行了验证.研究结果表明:石灰石相较于其他岩石更易产生岩粉,其主要来自于爆破形成的粉碎区,机械破碎中的矿石整形,钻孔岩屑及软弱夹层;通过优化爆破破碎过程,采用空气间隔不耦合装药、现场混装装药和合理优化爆破参数等方式,可以控制粉碎区大小,使爆破级配更为均匀,从而减少爆破岩粉.

实时高温下与热处理后砂岩动态拉伸特性研究

为了开展实时高温下及加热冷却后岩石动态力学性质的对比研究,利用自行设计的加热装置结合SHPB系统对两种温度状态砂岩的动态拉伸特性进行试验研究,处理温度为常温(25℃)～600℃共7组.结果表明:砂岩的率效应在两种温度状态下都存在,热处理后的砂岩拉伸强度除100℃外都比常温状态小,且随着热处理温度的增大,拉伸强度减小,温度会影响试样的破坏形态.高温下砂岩的拉伸强度除600℃外都比常温状态大,且拉伸强度随着温度的升高先增大后减小,加载率对破坏模式起主导作用.高温下的热膨胀作用会抑制裂纹相互连接,使得岩石结构更

爆破振动对高层框架-剪力墙结构的影响

为了明确爆破冲击波对高层建筑结构构件及其施工安全性的影响,以广东以色列理工学院二期校区爆破工程为例,基于建筑物地表及典型结构构件监测数据,采用回归分析对高层建筑典型结构构件振动规律进行研究.研究表明:随着距爆源水平距离的增加,垂向、径向和切向振动速度逐渐减小且衰减趋势相似;结构局部振速存在放大效应,在距地高程相同的情况下,随着结构构件与地基的自振频率比值的减小,其振速比逐渐增大;在结构构件与地基的自振频率比值相同的情况下,随距地高程的增加,结构构件与地基的振速比呈线性增长.
