畢奧波-
In chapter 5, based on biot ' s theory for anisotropic fluid - saturated porous media, the rayleigh waves in orthotropic non - viscous fluid - saturated porous media are studied
在第5章中，以biot的各向異性液飽和多孔介質理論為基礎，研究了正交各向異性無粘流體飽和多孔介質中瑞利波的傳播特性。 -
It consists of two parts : the first part ( chapter 2, 3, 4, 5 ) studies the characteristic of elastic waves and surface waves in orthotropic fluid - saturated porous media using biot ' s theory which is based on the substitutive model. in the second one ( chapter 6 ), a new three - dimensional meso - calculating model, which is more coincided with the inner action mechanism of porous media, is proposed. based on this model, the elastic wave propagation in fluid - saturated porous media under longitudinal impacting is discussed
論文主要分為兩大部分：第一部分基於替代模型的biot理論，對各向異性介質中平面波以及表面波的傳播特性進行了研究；第二部分從細觀層次出發，提出了一個更加符合含液飽和多孔介質內部作用機理的三維細觀計算模型，並對縱向沖擊載荷作用下液飽和多孔介質中彈性波的傳播規律進行了討論。 -
In spite of modifying coefficient, a modifying term is used to modify brandt ' s theory of sphere grain model ; this term ' s expression has been acquired, and the result is identical to biot - geertsma ' s theory in form and quantity, in which the two classics theories is in perfect harmony. it is also confirmed that the constitutive relation of carroll and n. katsube theory, and the bulk modulu of kuster scattered waves are identical to biot theory
在工程中的絕大多數情況下，該結果與biot - geertsma理論的結果在形式及數值上幾乎完全一致，從而使這兩個不直接相關的經典理論較好的統一起來。 （ 3 ）在土動力學中常用的不排水條件下，分別證明了carroll的應力-應變關系中不排水體積模量、 kuster散射波理論的體積模量與biot - geertsma理論是完全一致的。 -
In fact, the constitutive models employed in both methods could not re - produce the dynamic behaviour of soil to non - proportional cyclic loading, such as waves loading. to simulate dynamic responses of elastic, visco - elastic and elasto - plastic sea beds, linear and / or non - linear numerical models based on generalized biot ' s theory are developed together with stable and effective algorithm. the difficulty in numerical computation made the generalized biot ' s theory be difficult to be put into practice in the field of geotechnical engineering
上述兩種方法採用的土體本構模型都不能再現砂土在暴風浪等非比例加載條件下的動力特性，本文基於廣義biot理論提出了波浪作用下海床線性或非線性動力響應的耦合計算模型與穩定、高效數值演算法，分別針對土的彈性、粘彈性與彈塑性本構關系，對海床的動力響應進行了有限元數值模擬與分析。 -
Based on biot ' s consolidation and simplified sea - bed to two dimensional sea - bed, numerical simulation about the response of sea bed to waves is developed. the assumption was wielding, such as linear wave loading, linear elastic skeleton of soil and darcy ' s law flow
本文選用了基於biot固結理論，將海床進行二維簡化的情況下海床對波浪響應的數學模型，在模型中採用下列假定：線性波浪作用，線彈性土骨架，孔隙流體的流動滿足達西定律。
