【摘要】：該文應(yīng)用修正光滑粒子方法(CSPM)和黎曼解對(duì)光滑粒子流體動(dòng)力學(xué)(SPH)方法進(jìn)行了修正,將修正后的SPH數(shù)值方法應(yīng)用到波浪與開孔沉箱結(jié)構(gòu)相互作用的研究中,采用結(jié)構(gòu)完全瞬態(tài)動(dòng)力分析方法對(duì)有頂板開孔沉箱的動(dòng)應(yīng)力響應(yīng)問題進(jìn)行了時(shí)域研究,研究了有頂板開孔沉箱開孔板動(dòng)應(yīng)力的分布情況,討論了動(dòng)應(yīng)力峰值與頂板高差影響因素間的關(guān)系,得出了等效應(yīng)力沿著開孔板中心位置向兩側(cè)非線性變化的結(jié)論,為開孔沉箱結(jié)構(gòu)設(shè)計(jì)提供了一定的參考。
[Abstract]:In this paper, the modified smooth particle method (CSPM) and Riemann solution are used to modify the smooth particle hydrodynamics (SPHs) method. The modified SPH numerical method is applied to the study of the interaction between waves and caisson structures.The dynamic stress response of caisson with roof opening is studied in time domain by using the method of complete transient dynamic analysis. The distribution of dynamic stress of caisson with roof opening is studied.The relationship between the peak value of dynamic stress and the influence factors of roof height difference is discussed. The conclusion that the equivalent stress changes nonlinearly from the central position of the perforated plate to the two sides is obtained, which provides a certain reference for the structural design of the caisson.
