alluvial valley meaning in Chinese
冲积谷
冲积河谷
Examples
- In loessal regions and alluvial valley fills of the western united states, both surface soil and subsoil are commonly friable .
在美国西部黄土区和冲积河谷里，表土和底土一般是容易破碎的。 - The results of studying indicate : the solutions are convergent even for the alluvial valley of small depth - to - width ratio and it has high precision
验证结果表明，解答在小深宽比盆地情况下是收敛的，而且收敛的数值结果具有足够的精度。 - ( 3 ) comparison analysis for antiplane surface motion features between the circular - arc cross - section alluvial valley and the single overburden layer is investigated in details in this paper
( 3 )为了更深入地研究了一般圆弧状沉积盆地的出平面地表运动特征，本文与已有的软土单覆盖层解析结果做了对比分析。 - ( 2 ) there are no reports on the analytical solution of antiplane scattering of shallow circular - arc cross - section alluvial valley because of limit of the special functions , although it possesses practical engineering values
( 2 )浅圆弧型沉积盆地是一种更具有工程实际意义的局部场地，关于这种典型场地出平面散射的解析结果尚未见报道。 - The notable torsion effects of the surface ground motion above the alluvial valley are illustrated and the torsion effects become stronger as the frequency of the incidence is higher . ( 4 ) antiplane surface motion of the underground circular soft inclusion and the underground homogeneous soft interlayer is investigated in this paper . the results indicate : surface displacement amplitudes just above the soft inclusion of small depth - to - width ratio is amplified and soft interlayer of small depth - to - thickness ratio is amplified to a certain degree , and moreover , the latter is lower limit of the former
结果表明：垂直入射时，小深宽比软夹塞上方地表位移幅值有较大的放大，小深厚比软夹层的地表位移幅值也有一定的放大，且后者为前者的下限；波接近掠入射时，软夹塞正上方地表点和软夹层的中国地震局工程力学研究所硕士学位论文一地表位移幅值都没有放大，而软夹塞迎波面一侧地表点的位移幅值会有一定的放大；软夹塞上方的地表位移运动有较强烈的扭转效应，且此扭转效应随入射波频率的增高而增强。
