The purpose of this study is to analyze the overall condition of the foundation for the three storied stone pagoda of Bulguksa temple in GyeongJu. As a research method, exploration of the electrical resistivity, refraction seismic, surface wave exploration, GPR exploration, Reputation loading test. The results of the investigation, the range of the foundation was formed in foundation stone outskirts of 1.5 ∼ 2.0m. It was confirmed to be about 2.0m depth. The depth of the foundation becomes shallower from the base portion to the outside. And the bearing capacity of foundation was sufficient conditions to weight. It can sufficiently support the weight of pagoda. And, the result of this investigation becomes basis data for repair work.

The purpose of this study is to analyze the cause of damage to the three storied stone pagoda of Bulguksa temple in GyeongJu. This report is attempted to making reinforcement and conservation plan through investigating and analyzing the cause of damage to that. The damage is caused by occurring of stress, degrading of stone strength, changing of underground soil structure, natural disasters and so on. Compressive stress, shear stress, bending stress and lateral pressure affected to the pagoda since built up. Ultrasonic examination data tells the strength of the stone. According to this result, strength of the stereobate stone materials is enough to support the weight of the upper ones. But we could found many other factors of the damage could consider, for example the problems occurred on building the pagoda construction and the weakness of the stone material(soft rock). And many environmental factors being changed in soil structure(subsidence of soil and degradation of bearing power of soil and freezing and melting of soil) can be seen as the cause of the damage. Natural disasters like earthquake, lightning and heavy rain were also thought to give direct impact to the damage. At last Concentration of compressive stress caused the crack and exfoliation on the stone materials and shear stress, bending stress and lateral pressure were main causes of the stereobate stone materials shearing.

경주국립공원 불국사 주변 사찰림을 중심으로 식생구조를 파악하기 위하여 42개의 조사구(단위면적 100m2)를 설치하여 식생조사를 실시하였다. Classification 분석 중 TWINSPAN 기법을 이용하여 군락분리를 시도한 결과, 군락 I은 소나무-잣나무군락, 군락 II는 소나무군락, 군락 III은 소나무-단풍나무군락, 군락 IV는 단풍나무-소나무군락으로 최종 분리되었다. 식생구조 분석결과 경주국립공원 불국사 주변 사찰림은 소나무가 우점하고 있었다. 군락 IV는 소나무 군락에 단풍나무가 유입되면서 단풍나무-소나무군락으로 군락이 변한 것으로 파악되었다. 그러나 최근 자연발생적으로 아교목층과 관목층에 굴참나무, 갈참나무, 졸참나무, 신갈나무가 확산되고 있어 추후 소나무와의 경쟁이 예상된다. 본 조사지역의 산림식생의 임령은 소나무가 우점종인 산림은 30~100년 내외인 것으로 밝혀졌으며, 단풍나무는 30~36년의 수령을 가진 것으로 나타났다.

Temple with Multi-Buddha's Pavilions is a temple consisting of more than 2 Buddha's Pavilions. Individual Buddha's Pavilions tend to form distinguished area, or to keep independent axis from other Buddha's Pavilions. This study is to understand the philosophy of layout of individual Buddha's Pavilions located in the Temple with Multi-Buddha's Pavilions. To investigate a relationship to layout of individual Buddha's Pavilions on the basis of Buddhism doctrine makes us to understand philosophies about temple layout which temple constructors had. Bulkooksa, a temple having several pavilions placed in parallel, integrates diverse philosophies such as Vairocana Buddha-Ksetra from Vairocana Buddha's Pavilion, Sakyamuni Buddha-Ksetra from both Sakyamuni Buddha's Pavilion and two stupa, and Amitayus Buddha-Ksetra (Sukhavati) from Amitayus Buddha-Ksetra Pavilion. Sakyamuni Buddha's Pavilion and Amitayus Buddha's Pavilion are placed east to west in parallel, and Vairocana Buddha's Pavilion is placed behind them. Beobjusa, a temple having several pavilions placed cross axis, combines three axes such as the first, main axis linking Kumkang Gate - Chunwang Gate - Palsang Pavilion - Amitayus Buddha's Pavilion - Sakyamuni Buddha's Pavilion, the second axis linking Palsang Pavilion -Maitreya Pavilion, and the third axis linking Amitayus Buddha's Pavilion - Avalokiteshvara Pavilion. Relationship among each Buddha's land is clearly expressed by means of this cross axis layout of Buddha's Pavilions, reflecting a philosophy of rebirth in Nirvana that Wonhyo and Eusang propagated. Buseoksa, a temple having several pavilions placed the before and the behind, combines three Buddha's lands such as Maitreya Buddha-Ksetra, Amitayus Buddha-Ksetra and Vairocana Buddha-Ksetra, by means of arrangement of Maitreya Pavilion, Anyang Pavilion and Amitayus Buddha's Pavilion at bended axis, and east facing Amitayus Buddha. By investigating the philosophy of Temple layout with Multi-Buddha's Pavilions in this study, Buddha's Land conception, for people, that ancient Korean temples have, is understood.
