viscoelastic solutions with applications to semi-infinite soil subjected to vertical force 豎向力作用在粘彈性土體內(nèi)部時(shí)的解答與應(yīng)用
Using elastic-viscoelastic correspondence, the viscoelastic solutions are obtained by inversion of laplacian transform 利用對(duì)應(yīng)原理,經(jīng)過(guò)反變換得到粘彈性力學(xué)解答。
Thirdly, a simplified model neglecting the radial displacement of saturated soil is established and an analytical solution for vertical vibration of the soil-pile system is obtained . by comparison the solution with available viscoelastic solution, the differences are illustrated as well as its applications 3、建立了飽和土中忽略徑向運(yùn)動(dòng)影響的簡(jiǎn)化模型,得到簡(jiǎn)化模型下樁土縱向耦合振動(dòng)解析解,并與考慮徑向運(yùn)動(dòng)影響的模型及胡昌斌的模型加以比較,分析了幾種模型的異同及適用性。
Constants of viscoelastic material described by prony series constitutive relation are deduced . for the case of interface crack in viscoelastic material infinite board under the load of mixed type 1, 2 and type 3 respectively, laplace transform is used to change the basic equations from time domain to frequency domain . according to the corresponding principle, viscoelastic solution can be obtained by substituting the viscoelastic constant into elastic one 對(duì)本構(gòu)關(guān)系由prony級(jí)數(shù)描述的含界面裂紋的雙粘彈性材料無(wú)限大板,分別研究了受、型混合外載及型外載的情況,用laplace變換將其時(shí)域基本方程變換到頻域,根據(jù)對(duì)應(yīng)原理,將粘彈性常數(shù)代入彈性解,得到頻域中的粘彈性解。
