    • PURPOSE: A construction method of a tension type single span cable-stayed bridge is provided to cost-efficiently construct a cable-stayed bridge by changing compressive force applied to a girder into tensile force. CONSTITUTION: A construction method of a tension type single span cable-stayed bridge is as follows. First deck segments are installed to be directly supported to two towers(110) separated from each other using inclined cables. Multiple deck segments are consecutively installed on the first deck segments using additional inclined cables. When the deck segments to be connected to each other are adjacent to each other, jacks(200) are installed between the towers and the first deck segments. Key segments(400) are arranged between the deck segments to be connected to each other, and the installed jacks are powered to continuously connect the deck segments to each other. Tensile force is applied to the connected deck segments. [Reference numerals] (AA) First step; (BB) Second step; (CC) Third step; (DD) Fourth step
    • 目的:提供一种张力式单跨斜拉桥的施工方法,通过改变施加在大梁上的压力作为拉力来成本有效地构筑斜拉桥。 构成:张力式单跨斜拉桥的施工方法如下。 第一甲板段被安装成直接支撑到使用倾斜电缆彼此分离的两个塔架(110)。 使用额外的倾斜电缆将多个甲板段连续地安装在第一甲板段上。 当彼此连接的甲板段彼此相邻时,千斤顶(200)安装在塔架和第一甲板段之间。 钥匙段(400)布置在彼此连接的甲板段之间,并且安装的千斤顶被供电以将甲板段彼此连续地连接。 拉伸力施加到连接的甲板段。 (附图标记)(AA)第一步; (BB)第二步; (CC)第三步; (DD)第四步

    • PURPOSE: A construction method for a partially anchored cable-stayed bridge using a tensional member and a lateral anchoring block is provided to reduce the sectional area of a main span deck segment by reducing the size of maximum compressive stress applied to the section of the main span deck segment. CONSTITUTION: A construction method for a partially anchored cable-stayed bridge using a tensional member and a lateral anchoring block comprises the following steps: separately installing first and second main towers and separately installing first and second anchorage to a lateral span side; connecting first lateral span deck segment and a first main span deck segment using a compression cable; separately connecting a tensional cable extended from the first and second anchorages to second and third main span deck segments; installing lateral anchoring blocks (500) in the lateral sides of the second and third main span deck segments; and mounting a tensional member (430) in between the lateral anchoring blocks for tensioning and anchoring.
    • 目的:提供一种使用张紧构件和横向锚固块的部分锚固斜拉桥的施工方法,通过减小施加在主跨段的主段的最大压应力的尺寸来减小主跨度板段的截面面积 跨度甲板段 构成:使用张紧构件和横向锚固块的部分锚固斜拉桥的施工方法包括以下步骤:分别安装第一和第二主塔,并将第一和第二锚固单独安装到横向跨度侧; 使用压缩电缆连接第一横向跨度甲板段和第一主跨度甲板段; 将从第一和第二锚固件延伸的拉伸电缆单独连接到第二和第三主跨度板段; 在第二和第三主跨度甲板段的侧面安装侧向锚固块(500); 以及将张紧构件(430)安装在侧向锚固块之间用于张紧和锚固。

    • PURPOSE: A vibration control structure of a cable bridge is provided to effectively apply a damping structure to a long span bridge by installing dampers in the reinforcement girder side and main tower side of a cable in a cable bridge. CONSTITUTION: A vibration control structure of a cable bridge comprises a main tower (100), a reinforcement girder (200), and a plurality of cable bridge cables (300). The joint parts of the cable bridge cables and the main tower are installed with a main tower side damper. The joint parts of the cable bridge cables and the reinforcement girder are installed with a reinforcement girder side damper. The main tower comprises a main body (110) and a storing part (120). The storing part is protruded to the lateral side of the main body in order to store the main tower side damper.
    • 目的:提供电缆桥梁的振动控制结构,通过在电缆桥架中的电缆的加强梁侧和主塔侧安装阻尼器,有效地将阻尼结构应用于长跨度桥梁。 构造:电缆桥梁的振动控制结构包括主塔架(100),加强梁(200)和多个缆索桥接线缆(300)。 电缆桥电缆和主塔的接头部分安装有主塔侧阻尼器。 电缆桥接电缆和钢筋梁的连接部分安装有钢筋梁侧阻尼器。 主塔架包括主体(110)和存放部(120)。 存储部分突出到主体的侧面以便存储主塔侧阻尼器。
