根据一些强夯工程的实测资料,探讨了夯沉量的变化规律,并分析发现地基内部孔隙水压力、竖向压应力的变化特点,由此结合碰撞理论、波动理论和固结的基本理论,论述了强夯击数对强夯效果的作用,得出了一些很有意义的认识。
On the basis of physical and mental demands of passengers,formula of how to calculating the long-wait time and the maximum shocks of passengers were derived.
信息的完整决定着控制的优良,该文介绍了一种全部采用数字键盘的电梯群控模型,针对该模型,在乘客两种不同需求的基础上,推导了乘客的最长候梯时间和最大冲击数的计算公式,采用规则模糊推理,实现层站召唤的合理分配,仿真实验对常规电梯群控系统和全数字群控系统做了比较,结果表明,在正常客流模式下,乘客的乘梯时间和经受的冲击数较常规的群控系统有降低,特别是强度较轻的客流模式效果更为明显,为研究符合乘客利益的电梯群控系统奠定了基础。
About the problem of the interface determination of strongly weathered granite in the south of Fujian province, the quantitative evaluation can be performed by the blow counts N of standard penetration test(SPT), but the correction of N has different definitions from various technical regulations.
