alluvial valley 中文意思是什麼
alluvial valley
解釋
沖積谷-
In loessal regions and alluvial valley fills of the western united states, both surface soil and subsoil are commonly friable.
在美國西部黃土區和沖積河谷里，表土和底土一般是容易破碎的。 -
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
結果表明：垂直入射時，小深寬比軟夾塞上方地表位移幅值有較大的放大，小深厚比軟夾層的地表位移幅值也有一定的放大，且後者為前者的下限；波接近掠入射時，軟夾塞正上方地表點和軟夾層的中國地震局工程力學研究所碩士學位論文一地表位移幅值都沒有放大，而軟夾塞迎波面一側地表點的位移幅值會有一定的放大；軟夾塞上方的地表位移運動有較強烈的扭轉效應，且此扭轉效應隨入射波頻率的增高而增強。 -
After that, antiplane surface motion features of the shallow alluvial valley of small depth - to - width ratio are investigated in details. the results indicate that surface displacement amplitudes of alluvial valley will not reduce when the alluvial valley become shallow. the maximum amplitudes will move to high frequency with depth - to - width ratio becoming small
在此基礎上，對小深寬比的淺圓弧型沉積盆地出平面地表運動特徵做了較深入的研究，結果表明盆地地表位移幅值不會因變淺而減小，最大反應會隨著盆地深寬比的減小而向高頻移動。 -
( 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 ）為了更深入地研究了一般圓弧狀沉積盆地的出平面地表運動特徵，本文與已有的軟土單覆蓋層解析結果做了對比分析。 -
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
驗證結果表明，解答在小深寬比盆地情況下是收斂的，而且收斂的數值結果具有足夠的精度。 -
( 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 ）淺圓弧型沉積盆地是一種更具有工程實際意義的局部場地，關于這種典型場地出平面散射的解析結果尚未見報道。 -
Several typical sites are chosen in this paper in order to investigate the main points of wave function expansion method applied to elastic wave scattering problems. antiplane scattering analytical solution for the alluvial valley of shallow circular - arc cross - section is investigated, which has practical engineering value
