In case of having no consideration for pore pressure, we may underestimate earthquakes in seismic analysis of fill dam. because we can not consider hydrodynamic pressures induced by earthquakes. Nevertheless, there are few actual results on hydrodynamic pressures variation due to the principal variables of seismic analysis of fill dam. So, in this study we study earthquake-pore pressure interaction performing divers variable analysis, as considering Sesimic load-Pore Pressure. 필 댐의 내진해석은 간극수압을 고려하지 않을 경우에는 지진에 의한 동수압을 고려할 수 없기 때문에 지진력을 과소평가할 수 있다 그러나 현재까지도 필 댐의 내진해석에서 주요 변수에 따른 동수압의 변화는 연구 실적이 많지 않다. 따라서 본 연구에서는 지진하중과 간극수압을 모두 고려하는 경우에 대해 다양한 변수분석을 수행하여 지진과 간극수압의 상호작용을 알아보았다.

Nonuniform temperature distribution due to hydration heat induces thermal stress in mass concrete. At early ages, such thermal stress may induce thermal cracks which can affect on the durability and safety of the structure. Therefore, in Shin-chon Bridge Project, the field measurement of hydration heat for the massive concrete footings(20×20×3.5m) was carried out. It was shown to be possible to construct the massive concrete footing successfully by application of pipe cooling system. And the measurement results showed that standard code for concrete practice was very agreement.

Lately, there are actively proceeding in making a plan for subway construction, a high-speed railway construction and a expansion of road and also all kinds of large-scaled construction in Korea. Construction works were delayed from noises and vibrations occurred by usage of a large-sized construction equipments and driven and also blast or there were often stopped from them under construction. Therefore, this study was modeling operation of the cyclic loading and conforming effects from grasping displacement-changing method through a variable analysis.
