Based on the principle of dspi , a kind of visual system was designed in this dissertation . which can be used in testing the off - surface displacement and deformation of the rough surface . at the same time , a multi - purpose optical metering system which contains this visual system was created and manufactured 基于dspi原理,論文吸收統計分析思想,相對完善了該技術的實用技術體系,設計了一種dspi應用光路,該光路可用于粗糙表面離面位移和形變檢測,并依托此光路設計了一套多功能激光光電實驗系統。

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征做了較深入的研究,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。

( 5 ) antiplane surface motion of underground circular hard inclusion and underground homogeneous hard interlayer is investigated . the results indicate : the surface displacement amplitudes just above the underground circular hard inclusion is reduced , while surface motion on both two sides are significantly amplified when the vertical waves are excited . the surface motion on the side o 結果表明:波垂直入射時硬夾塞上方地表位移幅值處于減小狀態,但在兩側出現放大,波斜入射時硬夾塞的迎波一側地表易出現一定的放大:硬夾層上的地表位移幅值在多數情況下呈現一種放大作用,對深厚比較大的硬夾層放大作用易出現在低頻:地下硬夾塞上的地表運動沒有明顯的扭轉效應。

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,且后者為前者的下限;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。

Based on the error theory of point measurement are the identifying of the error range set , sketch of the error ellipse , analysis on displacement of the monitoring sites and error detection , providing a fundamental theory infrastructure for dynamic assessment of surface displacement and gray prediction 根據點位測量的誤差理論,確定定誤差值域范圍,繪出誤差橢圓;對各監測點進行位移與誤差判別分析,為地表位移動態分析和灰色預測提供理論基礎。

The anchorage force of bolt , the displacement of deep surrounding rock , and the surface displacement of the gateway were comprehensively observed , indicating that the testing entry affected by dynamical mining pressure still keeps stable , achieving a good supporting effect 錨桿受力、圍巖深部位移、頂板離層及巷道表面位移綜合觀測表明,受回采動壓影響后,試驗巷道穩定,支護效果好。

And ground surface displacement and deformation in the 1277 mining area at wenjiaping mine were analyzed by using this model 并采用該模型對文家坪磷礦1277采區地表巖體移動變形進行了具體的計算分析。
