Usually the seismic stability analysis of slope uses the pseudostatic analysis considering the inertial force by the earthquake as a static load. Geostructures such as slope include the uncertainty of soil properties. Therefore, it is necessary to consider probabilistic method for stability analysis...

사면과 같은 지반 구조물은 어떻게 지반정수의 불확실성을 고려해야 하는가? | 지진에 대한 사면안정 해석은 지진에 의한 관성력을 정적하중으로 고려하는 유사정적해석을 널리 사용하고 있다. 사면과 같은 지반 구조물은 지반정수의 불확실성이 포함되어 있어 확률론적 해석을 이용하여 지반정수의 불확실성을 고려해야 한다. 본 연구에서는 지반의 불확실성을 고려한 확률론적 사면안정해석을 수행하였으며, 구조물이 임의 수준의 지반 운동을 받을 때 파괴상태에 도달하는 확률을 그래프로 나타낸 취약도 곡선을 작성하였다. | |

사면의 신뢰성 해석에서 응답면기법이 적용된 이유는 무엇을 보완하기 위함인가? | 이러한 지반의 불확실성을 고려한 확률론적 해석은 해석시간이 오래 소요되므로 실무에서 적용하기 어려운 면이 있다. 이 점을 보완하기 위하여 사면의 신뢰성 해석에서 응답면기법이 적용되었다(e. |
