简介：作为一个挡土墙，门水注射板桩(PWISP)在2000出现在海岸工程。尽管有许多系统的方法，处理这个问题，在新结构上有在定义在二堆积之间的地压的因为困难的很少的集中。一个新方法在这篇论文被建议获得在PWISP之间的地压。对翻的稳定性分析作为后果列在后面。用FiniteElement分析(FEA)软件ANSYS，两个都，接触元素的土壤和那些的非线性的特征被考虑在接触表面上获得地压分发。基于FEA的结果，Rankin“s理论和slip飞机理论，在堆积之间的内部表面上的地压的公式被给。作为对它起作用的外面的力量作为分析目标和地压假定PWISP，对PWISP翻的稳定性的方程被介绍。最后，一些参数对翻关于PWISP的thest能力被讨论，例如前面堆积，在二排堆积之间的距离，内部磨擦角度和地球的结合的嵌入的深度。结果证明结合和内部磨擦角度的增加将减少距离和嵌入的深度，并且因此对翻提高稳定性。明确地，当距离是最大的挖掘深度的1/3-2/3时，二排堆积在稳定性给最好的表演。

简介：这篇论文澄清单个价值分解分析(SVD)的显著性检验的本质，并且为测试SVD的联合模式的意义调查四条规则，包括平行分析，非参量自举，随机阶段的测试，和说出的一条新规则修改了平行分析。一个数字实验被进行到份量上在判定SVD的acoupled模式是否作为象样品尺寸，格子点的数字，和signal-to-noise比率那样的参数重要比较四条规则的表演变化。四条规则与格子点的数字的更低的比率更好执行到的结果表演取样尺寸。修改平行分析并且非参量自举最好表现放弃假联合模式，而是后者当样品尺寸不比格子点的数字大得多时，比前者好保留重要联合模式。仅仅当(1)在格子点的观察是时，平行分析和随机阶段的测试是柔韧的放弃假联合模式空间地uncorrelated，或(2)联合信号为平行分析是很强壮的并且不为随机阶段的测试是弱的。影响测试规则的精确性的原因被讨论。
