摘要： 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
摘要翻译：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
