在连续强降雨极端天气下,四川红层地区某高速公路填方路基发生滑坡,导致高速公路断道,影响车辆通行.为尽快恢复通车,需科学合理地分析滑坡成因,以便采用高效、经济、快捷的工程措施进行处治.在详细调研某路基滑坡变形破坏特征、物质结构特性的基础上,对其成因机制及稳定性进行分析,据此提出了处治方案和措施,得出在红层地区高速公路滑坡抢险救灾工程中,采用圆形截面抗滑桩治理方案,其可旋挖成孔,施工快捷,且支护效果好,可在较短时间内恢复通车,值得推广应用.

为分析瞬时最优控制算法对高耸建筑结构的减震效果,建立了高耸结构瞬时主动最优控制的分析模型,并利用Matlab语言编制了求解软件.根据计算数据验证其减震效果,通过对高耸结构模型的分析,提出了一种能同时控制高耸结构前n阶振型的瞬时最优Q、R矩阵形式.结果表明:瞬时主动最优控制对高耸结构具有明显的减震效果,采用的矩阵形式能有效控制前3阶振型.并且可以通过调整权重参数达到目标减振效果.当Q、R矩阵中α=1E8,β=0.1-0.9时,具有满意的减振效果.所需的最大控制力减震效果及作动器位置有关,减震效率越高,作动器
