应用三维有限元动力学的基本方法,结合NEWMARK积分方法逐步求解运动方程,对动载(FWD荷载)作用下多层弹性体系的响应进行了分析,并将计算结果和理论结果进行对比,表明计算模型合理,计算结果准确。利用上述计算模型,对于多种路面结构研究其在不同荷载周期下的动态反应规律。

Speed management is essential for ensuring the operating safety of highclassified highway. This paper discusses the setting, dissemination and implementation of speed limits based on the current state of speed management in China, and points out the concept of dynamic speed limits and the method of setting the dynamic speed limits according to highways characteristics, traffic volume, weather condition and accidents history. Finally, the paper puts an emphasis on the importance of traffic safety culture to the implementation of speed limits.

The generally road safety situation of highway net was evaluated through investigating road safety of some highways and analyzing accident patterns and causes. Some sections with high accident rate were found using road black spot identification technology. Then, accident causes related to highway features and traffic factors were analyzed. The characteristics of typical black spots were analyzed from the aspect of highway features and traffic devices. Running speed of vehicles on highways was measured in order to explain why over-speed driving always was primary accident cause.

以上海市罗山路工程为依托,在施工阶段逐层进行了测定,包括回弹弯沉、承载板测定路面当量回弹模量、各结构层底面应变状态等。通过测定数据的分析,研究半刚性基层沥青路面各结构层的贡献情况,对分析半刚性基层沥青路面结构的结构性能,进行路面结构的组合设计具有较大的参考价值。

对判断土工织物淤堵的梯度比试验从理论与试验两个方面进行了研究。本文在理论上推导得出了梯度比用于判断土工织物淤堵的适用条件;试验结果也揭示了梯度比指标失效的原因。在此基础上还提出了淤堵试验的改进方案,并给出了采用淤堵试验中的系统渗流速度和渗透系数作为土工织物淤堵判断指标的方法。
