在对Logistic映象数值计算的基础上,我们分析了一维单峰映象的逆轨道结构,证明了不同参数处逆轨道总数N（n）随求逆次数n而变化的递推公式。借此解析地求得了在倍周期区中h（f）≡0;在U序列RLR2l的m=3+2l周期点上h（f）=logαmp,其中αmp为方程αm-2αm-2-1=0的最大实根;在2j-1常和2j带交界处hj（f）=（1/2）jlog2,由此可得聚点μ∞处拓扑熵的标度指数t=0.449806…。在此基础上,我们还求得了混沌区的周期窗口,U序列RLaRb所对应的各点处的拓扑熵,以及hR*Q（f）=（1/2）hQ（f）的关系。证明是在M.S.S.规则和“＊”乘法则的基础上进行的。所以本文的结果对一维单峰映象是普适的。

膨胀土路堑边坡发生滑坡的主要原因是雨水的入渗。通过分析膨胀土路堑边坡的工程特点和破坏机理,考虑雨水的入渗的情况下膨胀力变化的规律,选用合适的本构模型,对膨胀土路堑边坡的各种增湿状态进行仿真模拟,根据不同的降雨条件对膨胀土不同的入渗深度,对膨胀力进行简化,建立简单合理的膨胀力变化模型。分析发现膨胀土路堑边坡稳定性主要受雨水入渗后膨胀土的含水量影响,浸水后膨胀土边坡的安全性明显降低。这也要求在膨胀土路堑边坡的设计过程中,不仅要选用合理的坡率,而且要重点注意路堑边坡的防护和排水措施。
