Media: China's 100,000-seater "dangerous bridges" roads and bridges need to be bridge maintenance | | | road in China _ news

　　Japan Fuji Business Journal December 1, original title: many roads and bridges into the maintenance period

According to Chinese media reports, China Road and bridge is close to 800,000, the bridge and the bridge nearly 90,000 of them, number and size of rank first in the world. But at the same time, many also entered a period of maintenance of the bridge. Right now, China's bridge from "construction" era "construction and maintenance" era go hand in hand. Bridge how to function the sound "was born", without the offending State "grows" and "patience" is becoming a need to address the issue.

Reform and opening up, China Road and bridge culminated, the bridge and bridge-building is rapidly advancing. According to incomplete statistics, China Road and bridge about 40% has been used for more than 20 years, low technical level of ill bridges account for 30%. Allegedly, there are 100,000 bridges in "dangerous bridges". Experts said the bridge and bridge construction in recent years of rising labor and material costs, bridge cost increase. But a lot of the quality and cost of the bridge is not consistent, even several years after the completion patch examples will be required. In the middle and small scale bridge, some from the use of inferior materials and surface subsidence deformation risk to cause, security, there are some hidden dangers.

With the expanding Chinese bridge span, and safety concerns. But because of the complex bridge structures, teeming with hard checking and data issues, and some bridges implement checks only for a long time, it is difficult to grasp the specific status of all bridges. In view of this situation, Zhoushan City, Zhejiang Province, Zhou Hou in Shanxi province at the time of the construction of the bridge took the lead in the introduction of integrated management of safety monitoring system. In addition, iron bridge company has been established in "bridge hospital", a bridge main span of 460 meters, all laid over more than 300 monitoring stations, remote monitoring bridge condition, and according to early detection of problems in maintenance and repair of "prescription."

日媒:中国存在10万座“危桥” 公路桥梁亟待维护|桥梁|中国|公路_新闻资讯

　　日本《富士产经商报》12月1日文章，原题：中国许多公路桥梁进入维护期

　　据中国媒体报道，目前中国国内公路桥梁已接近80万座，其中大桥和特大桥近9万座，数量和规模均居世界首位。但同时，许多桥梁也进入维修期。当下，中国的桥梁已从“建设”为主的时代进入到“建设与养护”并进的时代。桥梁如何功能健全地“诞生”、在不出问题的状态下“成长”和“长命”正成为需要解决的课题。

　　改革开放后，中国道路桥梁建设迎来高潮，大桥和特大桥建设也急速推进。据不完全统计，如今中国的公路桥梁约4成已使用20多年，技术等级低的带病桥梁占3成。据称，有10万座桥梁处于“危桥”状况。专家表示，近年来大桥和特大桥建设的人工和材料费用高涨，桥梁造价不断增加。但许多桥梁的质量与造价并不一致，甚至出现竣工数年后就需修补的事例。在中小规模桥梁中，也有一些因使用劣质材料和地表下沉等原因面临变形风险，安全上存在一定隐患。

　　随着中国的桥梁跨度不断扩大，安全性如今备受关注。但由于桥梁结构复杂、难检查和数据庞杂等问题，长期以来只能对部分桥梁实施检查，难以掌握所有桥梁的具体状况。鉴于这种状况，浙江省舟山市舟山西堠门大桥在建设时率先引进安全监控综合管理系统。另外，中铁大桥局集团公司已设立“桥梁医院”，一座主跨460米的桥梁，全线会敷设300多个监测点，远程监视桥梁状况，并可根据早期发现的问题提出养护修理“处方”。
