본 연구에서는 불포화토의 삼축시험시 응력-변형률 관계를 Bishop 응력으로 기술하여 분석하였다. 불포화토의 파괴포락선은 Bishop 응력으로 기술할 경우에 모관흡수력에 무관하게 유일한 관계를 나타내고 있었다. 특히 모관흡수력이 낮은 경우에는 선형적인 관계를 나타내며 실험치와 이론치가 잘 일치하고 있었다. 미소변형률 영역에서의 변형계수는 대체로 Bishop 응력에 따라 선형적으로 증가하는 추세를 보이고 있었다.

This study explores the characteristics of Elizabeth Bishop's poetry in comparison with the two of her closest friends and poets, Marianne Moore and Robert Lowell. Bishop's reputation has dramatically changed since her death. In the 1970s she was "a writer's writer's writer," and admired by a small group of poets or critics. Since 1990s, however, there has been a great shift in the evaluation of her poetry, which is so called "The Elizabeth Bishop Phenomenon." It does not seem to be an easy task to examine what has driven the phenomenon, and why she used to be a minor poet or "the most honored yet most elusive of poets" but now she has a widespread recognition by the academy and beyond it. The "intrinsic qualities" of Bishop's poetry, however, can be one of the main reasons why it took several decades for Bishop to become a central figure in the literary canon. Looking into her "intrinsic qualities," this paper discusses Bishop's "The Fish," "Roosters" through the Moore-Bishop relationship, and reads Bishop's "Armadillo" and "The Monument" through the Lowell-Bishop relationship. It also deals with letters, interviews, Moore's "The Fish," and Lowell's "Skunk Hour" and "For the Union Dead" to show the Bishop's deep and complex relationships with the two poets, and more importantly their differences. Bishop's poetry is difficult, "elusive," and sometimes "enigmatic," not because her texts are full of difficult words to understand but because there are the subtle interchange between perception and meaning, "the dynamics of keen feeling," the unresolved patterns, and the transient vision under the seemingly transparent surface of the texts.

본 연구에서는 불포화토의 삼축시험시 거동을 Bishop 응력으로 기술하여 분석하였다. Bishop 응력으로 기술한 $K_0$ 압축시 경로 및 최종값은 모관흡수력에 무관하게 유일한 관계로 나타나고 있음을 알 수 있었다. 불포화토의 파괴포락선은 Bishop 응력으로 기술할 경우에 모관흡수력에 무관하게 유일한 관계를 나타내고 있었다. 특히 모관흡수력이 낮은 경우에는 선형적인 관계를 나타내며 실험치와 이론치가 잘 일치하고 있었다. 그리고 Bishop 응력을 기술하는 변수 ${\chi}$는 이론적으로 일정한 값을 가지고 있음을 입증하였다. 파괴규준에서 축차응력이 0인 경우 정의되는 흡수응력은 모관흡수력에 대하여 선형적으로 증가하며 실험치와 이론치가 적절하게 일치하였다.

In this paper, Bishop theory performs longitudinal vibration analysis of Nano-beams. Its governing equation, due to integrated displacement field and more considered primarily effects compared with other theories, enjoys fully completed status, and more reliable results as well. This article aims to find how Bishop theory and Two-phase elasticity work together. In other words, whether Bishop theory will be compatible with Two-phase local/nonlocal elasticity. Hamilton's principle is employed to derive governing equation of motion, and then the 6th order of Generalized Differential Quadrature Method (GDQM) as a constructive numerical method is utilized to attain the discretized two-phase formulation. To acquire a proper verification procedure, exact solution is prepared to be compared with current results. Furthermore, the effects of key parameters on the objective are investigated.

흙댐 및 자연사면(自然斜面)의 안정해석(安定解析)에 가장 많이 사용(使用)되는 Fellenius방법(方法)과 Bishop방법(方法)을 비교검토(比較檢討)하여 다음과 같은 결과(結果)를 얻었다. 1. 정상침투상태(定常浸透狀態)에서 Bishop방법(方法)이 Fellenius 방법(方法)보다 안전율(安全率)이 11~29%정도(程度) 큰 값을 나타냈다. 2. Bishop방법(方法)이 Fellenius방법(方法)보다 안전율(安全率)이 증대(增大)되는 비율(比率)($F_B-F_F/F_F$)은 경사면(傾斜面)의 기울기가 느릴수록 감소(減少)하는 경향(傾向)을 나타냈다. 3. 침투(浸透)가 없을때와 있을때의 안전율(安全率)이 증대(增大)되는 비율(比率)($F_1-F_2/F_2$)은 경사면(傾斜面)의 기울기가 느릴수록 증가하는 경향(傾向)을 나타냈다.

This study was performed to investigate the minimum safety factor of embankment in consideration of seismic coefficient by the psuedo-static analysis The variables were cohesion, the internal friction angle, angle of slope, height of seepage, height of embankment, depth of replacement The results obtained were compared with those by Fellenius method, simplified Bishop method and Janbu method. The results were summarized as follows: 1.The increasing rate of the minimum safety factor with the increasing of cohesion appeared larger in Fellenius method and Bishop method than in Janbu method. And that with the increasing of the internal friction angle appeared the lowest value in Janbu method. The minimum safety factor was influenced larger on the internal friction angle than on cohesion. 2.The variation of the minimum safety factor with the height of seepage at 0m and 5 m was nearly similar to Fellenius method, Bishop method and Janbu method. On the other hand, it was decreased suddenly at 25 m. 3.The minimum safety factor with the height of embankment was decreased remarkably under 10 m with the increasing of seismic coefficient. But, it was decreased slowly more than 10 m. As the height of embankment was low, the influence of cohesion appeared larger. 4.In heigher case of the depth of replacement, the phenomenon of reduction of the minimum safety factor appeared remarkably with seismic coefficient increased. And in lower case of the depth of replacement, the minimum safety factor was similar in Fellenius method and Bishop mehtod. But it appeared larger in Bishop method and Janbu method than in Fellenius method with the depth of replacement increased. 5.As the cohesion and the internal friction angle were large, the phenomenon of reduction of the minimum safety factor with the increasing of seismic coefficient appeared remarkably. Also, the influence of seismic coefficient in minimum safety factor appeared larger with the soil parameter increased. 6.When the seismic coefficient was considerated, investigation of the structural body on the slope stability appeared profitably in Fellenius method and Janbu method than in Bishop method.
