The present invention relates to a method for seismic reinforcement of an intake tower using a cable, capable of enabling an intake tower to be safely constructed by more effectively improving the seismic performance of an intake tower of which the bottom is submerged. The seismic reinforcement method includes the following steps of: (a) resisting the activity of an intake tower with a seismic load by adding frictional force from the bottom of an activity resistance plate to frictional force from the bottom of the intake tower through grid assembly plates arranged on the ground (G) around the intake tower in a ring form; (b) installing an intake tower bottom jacket bordered along the outer edge surface of the lower part of the intake tower while being inserted into the ground (G) to a predetermined depth (h), and functioning as an intake tower crack resistance plate by sharing compression force and tension force when a horizontal load caused by the seismic load is applied to the bottom of the intake tower as the compression force and the tension force; and (c) installing an activity resistance plate connector in a radial form between the intake tower bottom jacket and the inside of the activity resistance plate to prevent the position of the intake tower bottom jacket from being changed.
수중에 하부가 잠겨진 취수탑에 대한 지진성능을 보다 효과적으로 향상시켜 안전한 취수탑 시공이 가능한 케이블을 이용한 취수탑 내진보강방법에 대한 것으로서, 상기 취수탑 내징방법은 (a) 수중에 잠겨진 취수탑 주위의 바닥(G)에 링 형태로 배치되는 격자조립판에 의하여 활동저항판의 저면 마찰력이 취수탑의 저면 마찰력에 더해져 지진하중에 의한 취수탑 활동에 저항하도록 하는 단계; (b) 취수탑 하주 외주면을 따라 접하도록 하되 바닥(G)에 일정깊이(h) 삽입되며, 지진하중에 의한 수평하중이 취수탑 하단에 인장력 및 압축력으로 작용할 때 상기 인장력과 압축력을 분담하도록 하여 취수탑 균열 저항판 역할을 하는 취수탑하부자켓을 설치하는 단계; 및 (c) 취수탑하부자켓의 위치가 변동되지 않도록, 활동저항판의 내측과 취수탑하부자켓 사이에 방사형으로 활동저항판 연결재를 설치하는 단계;를 포함하도록 하게 된다.
