查询词典 section modulus

It is the effective foundation treatment of the deep soft soil ground. The finite element method analysis and the practice indicated that the reinforced foundation section can use composite modulus to computer the settlement, and the settlement of the center of the old road must be analyzed under different conditions.

有限元分析及工程实践表明，对于加固区可采用复合模量法来进行疏桩复合地基的沉降计算，而对于原路中心处应结合原路不同的工况合理选择分析方法，使情况更加接近实际。

On the basic assumption of WENCAL,using pre parameter method,the equation calculating multi element beam of different section and elasticity modulus on different groundsill are given in this paper. The programming language is QBASIC.

依据文克尔基本假定，利用初参数法推导出不同地基及不同地基梁截面弹性模量的多单元弹性地基梁计算公式，并用已编制的 QBASIC语言计算程序，通过实例计算，结果正确、合理。

Experimental results show that: bearing capacity of JPP is thirty percent higher than that of cast-in-place pile which has the same length and diameter with JPP. The deformation of JPP is controlled by core pile; axial force distribution of PHC is different with soil-cement; and their axial force ratio in same section is their elastic modulus ratio. Distribution of inner and outer friction resistance is similar; and the inner friction is about 1.62 times of the outer one; it is about the ratio of JPP diameter and PHC diameter. Furthermore, the relation between friction resistance and relative displacement is similarly hyperbolic; and the relation between dip resistance and displacement is also hyperbolic.

试验结果表明，JPP桩与同桩长、同桩经灌注桩相比承载力高30%以上；JPP桩变形由芯桩控制，管桩轴力分布与水泥土轴力分布规律不一致，但同一截面上管桩和水泥土的轴力比值约为其弹性模量的比值；内外摩阻沿桩身的分布规律类似，内摩阻是外摩阻的1.62倍左右，约为JPP桩直径和管桩直径的比值；桩侧摩阻力与桩土相对位移近似双曲线分布，桩端阻力和桩端位移也近似双曲线分布。

An equal cross-section blade was investigated and a finite element model was built parametrically. Geometrical parameters (such as length, width and thickness), material parameters (such as young's modulus and density) and speed of blade were considered as input random variables while the static frequencies and dynamic frequencies were output random variables. Combining the finite element method, response surface method and Monte Carlo method, the statistical properties and cumulative distribution functions of static frequencies and dynamic frequencies were obtained. Probability sensitivities analysis, which combined the slope of the gradient and the width of the scatter range of the random input variables, was applied to quantitatively evaluate the sensitivities of static frequencies and dynamic frequencies with respect to the random variables. The Scatter plots of structural responses with respect to the random input variables were illustrated how to adjust the values of the static frequencies and dynamic frequencies by changing input random variables.

文中以某试验台用汽轮机等直叶片为研究对象，考虑几何参数、材料参数和转速的随机性，通过有限元参数化建模，将确定性有限元方法、响应面方法和Monte-Carlo模拟法相结合，从而获得了叶片静频、动频的统计特性和累积分布函数；同时考虑随机变量的梯度和离散范围对静、动频的影响，通过概率敏感性分析，定量地判断出叶片静、动频对随机输入变量的敏感性；通过绘制叶片静、动频与输入变量的散点图，定量地分析了如何改变随机变量以调整静、动频率的方法。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
