5月16日,宝兰高铁陕西段联调联试正式启动,标志着我国首条贯通丝绸之路经济带的高铁——宝兰高铁进入开通倒计时。宝鸡至兰州高速铁路全长401公里,其中,陕西境内45.7公里,设有隧道13座,桥梁15座,桥隧总长44.57km,占线路总长的97%,设计速度为每小时250公里。自2012年10月开工建设,计划今年年内开通运营。届时,宝鸡至兰州列车运行时间将由目前的7小时缩短至2小时。
此次宝兰高铁陕西段联调联试区段为宝鸡南至天水南区间。联调联试项目主要包括轨道、路基、桥梁、列车空气动力学响应、电力牵引供电、通信、信号、客运服务系统、自然灾害及异物侵限检测系统、综合接地、电磁环境、振动噪声等综合测试和动态验收。为做好此次联调联试工作,西安铁路局专门成立宝兰高铁联调联试指挥部,组织建设、测试、施工、设计单位及路局相关专业处室、站段启动并推进联调联试工作,采取动车综合检测车进行综合检测试验、逐级提速试验、模拟场景试验、全线拉通试验等项目测试,确保全线达到运营条件,为正式开通运营打好基础。西安铁路局副总工程师徐建根介绍:联调联试对供电各种设备都要检测,对轨道的几何尺寸、线路的质量、一些运营的品质、脱轨系数等、对接入网、接入网导线、接入网压力都要进行检测,对信号设备、信号设备地面安装质量、数据等情况检测,通信设备我们用铁路专网,对通信品质也要进行检测,所有设备都要达到设计要求,符合运营要求,这样运营开通后再组织动态验收,组织运营实验,才能正式开通。
宝鸡至兰州高速铁路是国家中长期铁路网规划中“四纵四横”高速铁路网中徐兰高铁的重要组成部分。宝兰高铁建成后,徐兰高铁将全线贯通,连接已开通的兰新高铁,将打通中国高铁横贯东西的“最后一公里”,西北地区高铁将全面纳入全国高铁网。同时作为首条贯通丝绸之路经济带的高铁线,将连通丝路沿线的西安、宝鸡、天水、兰州、西宁、乌鲁木齐等多个主要城市,形成新丝绸之路上的高速通道,对加快西北地区与中东部地区的经贸合作、人文交流,促进丝绸之路经济带建设具有十分重要的意义。(中国日报陕西记者站)
