简介：这篇论文在地下的结构的横断面的地震抵抗设计描述一个通常使用的伪静电干扰方法。基于动态理论和地下的结构的颤动特征，错误的来源当使用这时，方法被分析。装载途径的传统的地震运动被aone维的土层反应应力在被区分然后变换成地震实时负担的一个方法代替。验证改进方法，分析结果的比较在地震用四个方法摇晃典型浅嵌入的塑造盒子的地铁车站结构下面为内力被进行：反应排水量方法，有限元素反应加速方法，有限元素动态分析方法和改进伪静电干扰计算方式。改进有限元素伪静电干扰方法在这建议纸为地下的结构的地震设计提供一个有效工具，这被显示出。近到那些的评估收益结果由有限元素获得了改进有限元素伪静电干扰方法提供的动态分析方法，和表演精确的更高的度。

简介：Xiangxi河盆，在华中在西方的湖北省定位了，是有水资源的不同类、复杂的分布的一个石灰岩地区常见的地形山脉马槽区域。这篇论文在这石灰岩地区常见的地形盆比较表面和表面下的洪水的特征，利用一个一个参数Darcian模型和传统的指数的模型。观察自记水位计和推断的水部件为表面和表面下的洪水是惊人地类似的。Darcian模型和指数的模型基于洪水产生过程的不同看法，与适合有适合有多重时间常数的仅仅衰退手足的一个单个时间常数，和后者的全部自记水位计的前者。由于石灰岩地区常见的地形媒介的anisotropy和异质，包括3S的使用的物理、化学的技术的联合(遥感，地理信息系统，全球放系统)方法被建议让提高的水文学调查在多山的区域估计并且描绘石灰岩地区常见的地形水资源。
