　　11month3Day,2020Annual 188bet mobile loginNational Science and Technology Reward Conference is held in Beijing，Hosted by the National Railway Group“High -speed railwayⅢ-type plate -free rail system technology and application”The project won the second prize of the 188bet mobile loginNational Science and Technology Progress Award.

　　The no -rail rail system is one of the core technologies of high -speed railways，Use layered concrete structures to replace traditional loose gravel bid bed，Have Gao Pingshun、High stability、Less maintenance and other advantages。Japan、Germany has long monopolized this technology。To meet the initial construction requirements of the high -speed rail，my country's introduction of technology from China has formedItype,II-type plate -free rail system，Due to the climate、Differences of geological conditions and technical limitations，High -temperature arches and low temperature breaks have appeared one after another、Structural layer 188betdeparture failure and not matching life、Drivers circuit information transmission is unstable and other problems，significantly affects the quality of the rail service，Maintenance cost far exceeds expected，Local location has to lower the speed to run。To comprehensively solve the above problems，Break foreign technology barriers，With the support of the state and ministries and commissions，Project for more than ten years of technical research，Collaborative innovation through industry, university, research，overcome the work of multi -layer structural systems under complex environmental conditions、Stable and reliable、Three major technical problems of high -efficiency construction，High -speed railway with independent intellectual property rightsⅢForm board -free rail system complete set of technology，my country has become the original country of the high -speed 188betrail no -rail system，is the high -speed rail“Go out”laid a solid foundation. The main innovation points of the project include:

　　1.Created the speed350New Methods Design of Design of System Design of Wudi Railway Structural System。Carried out a foot -ruler model test under different environmental conditions、Long -term monitoring test of real car power performance and operation status and complete massive data statistical analysis，Created a train high -frequency dynamic carrier、Temperature load、Basic deformation and other multi -field coupling effects without orbit static force refined analysis model，revealed the multi -layer structure deformation coordination mechanism and the law of vibration transmission，Proposed the global environment design method and parameter system，Solved the work difficulties of multi -layer structural systems under the action of complex environment and high -speed trains。

　　2.Invented the speed350New system for railway no -rail structure. Pioneer“Dive double -layer composite, vertical stress dispersion”Non -Rail Rail Composite Structure System，Realized stress release、Rail geometry maintenance and the same life of each structure layer; innovate high elasticity、High -base frequency、High fatigue strength without orbit deduction technology，Excandes the steel rail buckle pressure and padding of the steel rail buckle and pads under large deformation conditions、High -frequency resonance problems; innovated multiple insulation technologies without rail systems in the environment of the transient crossing strong magnetic field and rail circuit continuously;。

　　3.Innovative speed350kilometers of high -speed railway -free rail structure system High -precision and efficient construction new technology。The first pioneering two -way pre -stress track 188betboard high -precision and high -efficiency intelligent manufacturing technology based on the current method of running water units，Research and development of a complete laid equipment based on inertial navigation and rail testing network，Based on the design space of design、Digital construction technology of non -rail -free rail structure system with Gao Pingshun as the core，solved the technical problem of the millimeter -level efficient construction technology without orbit。

　　Project formation standard19Presides the preparation of international standardization organizations (ISO) Non -rail system standards; obtained invention patents32item, practical new type66, of which international patents8item; software copyright3item; publishing monograph4Ministry, publish papers170Yu chapter;1item, first prize3item, China Patent Outstanding Award3item。The results of the project are currently in Beijing、188bet loginJingxiong、Shanghehang and other dozens of high -speed rail line promotion and application，Mileage exceeds1.210,000 kilometers, the speed of successful development for the Zhengxu high -speed rail420kilometers of intersection and heavy joint comprehensive test provides solid support，and applied at high -speed rail projects such as Yawan, Indonesia，It is the only one to date“Go out”The high -speed rail no rail system，The results reached the international leading level as a whole。
