User Equilibrium in a Disrupted Network with Real-Time Information and Heterogeneous Risk Attitude
User Equilibrium Disrupted Network Real-Time Information Heterogeneous Risk Attitude
2014/10/22
The traffic network is subject to random disruptions, such as incidents, bad weather, or other drivers’ random behavior. A traveler’s route choice behavior in such a network is thus affected by the pr...

应当高度重视建筑环境声学的发展
建筑环境 声学
2014/9/18
听觉与视觉是人类感知外部环境并与外界进行信息交流的主要方式。无论从人类进化史上看，或者从整个人类的空间分布与数量上看，声音作为文化传承与信息交流主要媒介的时间与广度都要远超过文字与图像。
板材在拉深过程中,常出现杯壁被拉裂的现象。以前的学者针对这一问题主要致力于改变压边力来防治拉裂的研究。该文首先引入织构系数,然后利用弹塑性力学的相关知识和Hill屈服准则中材料常数与织构系数的关系,推导出板材拉深过程中织构系数与厚度增量的关系式。并经过算例验证该公式的可行性,得出可以通过改变板材的织构系数来降低板材拉深产生破裂的可能性。
在面外设置离散支撑,是建筑与桥梁工程设计中提高钢拱面外稳定性采用的有效措施。该文研究了面外支撑沿拱轴线非均匀布置时,箱型与圆管截面两铰拱的平面外弹性屈曲性能。该文首先将拱段间的相互约束作用等效为拱段两端的约束弹簧,采用数值拟合法获得了被约束拱段的平面外弹性屈曲荷载；此后借鉴压弯直构件端部弯矩与转角关系,提出了支撑间拱段的相互约束作用计算方法,并由此得到了面外支撑非均匀布置时,钢拱的平面外弹性屈曲荷...

盐岩巴西劈裂破坏声发射时序特征
盐岩 声发射 巴西劈裂 抗拉强度
2014/9/30
利用RMT-150B 岩石力学多功能系统和声发射监测系统，对盐岩巴西劈裂破坏过程中的变形与强度特征和声发射特征进行试验研究。试验结果表明：盐岩巴西劈裂破坏在峰值前的变形特征也存在类似单轴抗压试验的压密阶段、弹性阶段、屈服阶段和破坏阶段；在压密和弹性阶段声发射事件较少，能量较小，进入塑性阶段后，声发射振铃计数迅速增加，能量增大；当荷载超过承载能力后，试件突然劈裂破坏，残余应力迅速消失。试验表明，可通...
