부산지역 해안구조물의 재해특성에 관한 연구
- Abstract
- This study was performed to check the application criteria of the conventional techniques and to clarify the 2D/3D effects of storm surge, duration time and shallow water wave on the stability of coastal structure relate to the effects of uncertainty of typhoon duration and directional irregular waves.
Waves generated by typhoon in deep water propagate to shallow water with variation of wave characteristics (, ). The spectral/statistic parameters of the wave are difference between in the deep water and in breaking point. We confirmed the difference through field observed data (2003 ～ 2004, Busan new port).
This research made an analysis of the development of coastal structure and damage characteristic in consideration of hydraulic characteristics of the region of Busan district through 4-stage process.
In Chapter Two, this research examined the developmental history of the major coastal structure on Busan port and adjusted the present situation of the major outskirt facilities in Busan district.
This research also examined the developmental history of the coastal structures in relation to the breakwater and quay wall centering on construction cases in order to go over the developmental process of the coastal structures in Korea.
In Chapter Three, this research examined the hydraulic characteristic of the region in Busan waters and its present situation of the major damage.
This research analyzed the regional zoning in consideration of the submarine topology, and examined the characteristic of the major typhoon which had attacked the Busan district, conditions of wave design, storm surge level and characteristic of tidal generation, In addition, this research analyzed the present situation of Busan area ports and fishing port & its structures in Busan district in relation to the major typhoons which had an influence on Busan district including typhoon "Maemi".
In Chapter Four, this research conducted the factor analysis and establishment of alternatives using the repairs/numerical value simulation results in relation to the implosion stability of the low crest riprap mound breakwater of the eastern seawater at Busan new port, flooding at the coastal industrial complex caused by tidal wave at the Noksan national industrial complex, reduction plan for abnormal wave height within the port of Gamcheon, measures for reduction in moonlit waves at the revetment based on water-permeability compound cross section of the Namhangdong revetment, control of soft wave by virtue of the wavebreaker at the Yongho pier, and damage on the section of the bented east breakwater in the Daebyun port.
This research set up the characteristics of damage at the coastal structure of Busan area and its countermeasures by comprehensively examining the hydraulic characteristics, damage of coastal structures and developmental process of structures mentioned above.
In addition, this research adjusted the characteristics of damage to coastal structures through the major damage cases that occurred 7 regions in Busan district, suggested the appropriate alternative and basic data for alternative establishment of coastal structures.
Through the results above, this research discovered that the regional damage pattern & intensity occur differently consequent on the development of the coastal structures in Busan district; thus, it's imperative to set up the measures for comprehensive & planned maintenance of the coastal structures in time of design of the structures in waters.
