Based on the theoretical analysis of splitting mechanics and by the dynamic photoelasticity experiment , we studied the judgment how rock and concrete split under the affection of notched blasting . we built up the splitting mechanics model of rock and concretes under the affection of notched blasting . beyond all above , we gain the mechanism of notched directional splitting controlled blasting 本文在斷裂力學理論分析基礎上,通過動光彈爆破實驗,探討了在切槽爆破作用下巖石和混凝土的斷裂判據,建立了在切槽爆破作用下巖石和混凝土的斷裂力學模型,并由此得出切槽定向斷裂控制爆破機理。

According to this thought , two jobs are finished primarily . on the one hand , using the elastic results which got from experiment of photoelasticity , considering the model theory of elastic - plasticity and the deformation theory of plasticity , the paper propose hybrid methods for elastic - plastic problems . on the other hand , it can find out a new approach through combining present method with image processing 基于這種設想,主要做了兩方面的工作:一是實現了利用光彈性實驗的彈性解,結合彈塑性力學模型理論和塑性力學形變理論,求解彈塑性問題的混合解法;二是將上述方法與計算機的圖像處理系統相結合,實現方法上的進一步突破。

Most of the dynamic process data in the solid material , such as the dissemination of stress waves , the fold of stress waves , and the interaction of crack and stress waves can be acquired directly by the dynamic photoelasticity experiment 動光彈實驗能直接獲得固體介質中應力波的傳播、疊加以及裂紋與應力波相互作用的動態過程,可真實反映爆炸過程的信息與規律。

By means of the new method in this paper , the 3 - d photoelasticity analysis results of a bridge have been obtained , which well agree with the results of finite element method analysis 由本方法通過對大型橋梁工程結構的三維光彈性應力分析,其結果是合理的,與有限元計算進行比較,二者符合良好。

We studied the related parameter of notched blasting by the dynamic photoelasticity experiment simply . we also designed reasonable blasting parameter under the condition of laboratory 通過動光彈爆破實驗對切槽爆破的相關參數進行了初步探討,設計出在實驗室條件下的合理參數。

At the same time , we researched the method of the dynamic photoelasticity experiment . we designed a protection device and a trigger to pack the medicine structure synchronously 同時對動光彈爆破的實驗方法作了探索,設計出防護裝置和同步觸發裝藥結構。

Linking photoelasticity and computer technique and realizing the image automatic reduction is one of major directions to develop experimental mechanics 將光彈性方法和計算機相結合,實現光彈性圖像的自動識別功能是近年來實驗力學發展的主要方向之一。
