Description
Technical field
The present invention relates to a kind of railway construction of railways field of measuring technique, in particular to a kind of line of high-speed railway strong wind prison
It surveys and optimizes automatic search method of arranging net.
Background technique
High-speed railway plays increasing effect in present traffic and transport field, but present bullet train exists
It is very sensitive to the especially horizontal wind action of strong wind on high speed railway track in operational process, driving of the wind effect to train
Safety and on schedule operation bring great challenge.For example, and in " area Bai Lifeng " of China's Lan-xing Railway, since being open to traffic,
Because big wind-induced train derailing, capsizing case are up to 30, it is turned over 110, lorry；2003, because strong wind off-period is up to 50
Hour, cause 28,000,000 yuan of direct economic loss.
Therefore, in order to reduce the influence that strong wind is safely operated bullet train, current high-speed railway both domestic and external is taken precautions against natural calamities peace
Total system is generally used wind monitoring system, during the Design of High-speed Railway in China, sets to wind monitoring the related of system
The standard of setting has carried out specific regulation, the wind friction velocity set up including wind monitoring station, density of setting along the line, installation method and
The type etc. of sensor.But even if many high-speed railways are provided with wind monitoring system both at home and abroad, since wind effect causes
Train safety and the accident that runs on schedule but happen occasionally, the reliability and efficiency of operation of wind monitoring system are mentioned there are also very big
Between lift-off.
For example, set up gale monitoring system along the Shinkansen of eastern Japanese railway company, 2005, monitoring system just
Often in the case where operation, " spike of rice 14 " train but derails under the speed of 100km/h, causes 4 people dead, 33 people are injured, thing
The main reason for beam wind effect that investigation result shows that train is subjected to afterwards is exactly train derailment and overturns, and wind monitoring system is not
It can give warning in advance.Early in the end of the year 2004, just gale monitoring system has been installed in the air port along Xinjiang Railway to Urumqi Railway Bureau, China
System 2007, but still has occurred charming appearance and behaviour train derailing disturbing accident, causes 4 people dead, more than 30 people are injured.2013, typhoon
" Lepus " passes by, and wide Shenzhen and Hong Kong " Harmony " EMU that ShenZhen,GuangDong station originates all stops transport and is up to two day time, and typhoon is true
Active influence high-speed rail route operation but only have so short dozens of minutes, gale monitoring system it is overly conservative, this is also seriously affected
The efficiency that high-speed railway should play.
In conclusion the method for arranging of the monitoring point along the line of existing gale monitoring system, there is also following deficiencies:
(1) air measuring station is longitudinally arranged the reconnaissance foundation for determining shortage scientific quantification of position along high-speed rail route, and wind is surveyed in setting
Stand capture along least favorable wind monitoring point it is inefficient；Mountain area bealock, gorge are provided in " the Design of High-speed Railway specification " in China
Paddy, river valley wind monitoring point average headway be 1~5km, the sections spacing such as bridge, high embankment are then 5~10km；But in reality
Engineering-environment in, for the landform node of this category feature, often with the feature of " miniclimate ", high-speed rail route wind environment is to week
The variation of exclosure shape is very sensitive, the wind monitoring point of the 1~5km or 5~10km that suggest in specification layout principle it is excessively extensive,
Precision is lower, does not have the scientific basis of quantization, and practical operation difficulty is big；
(2) do not formed a set of normative and reasonable along the reconnaissance of wind monitoring station standard and method, air measuring station cloth at the scene
During setting, big with artificial feel and empirically determined composition, working efficiency is not high.
Therefore, letter wait needing it is a kind of in real time, accurately and efficiently gale monitoring system, especially setting in gale monitoring system
During vertical, it is basis and the premise of whole system efficient operation that the optimization of monitoring point, which is arranged net, along the line, for High Speed Railway Trains
Traffic safety and on schedule operation be vital.
