Research On Subway Monitoring Method Based On CPⅢ Measurement

With the rapid development of rail transit,high-speed rail and subway have become the common way of travel.As one of the main means of transportation of modern city transportation,subway is very important for the convenience of people.During the subway construction and operation phase,All need to deform the subway structure and track,Especially horizontal displacement monitoring,Its standard precision is higher,It is very difficult to achieve the accuracy of the method and technical means.In actual measurement,the method of precision conductors is used to monitor horizontal displacement.The method is difficult to measure,The workload is also large and the accuracy is difficult to guarantee.This paper adopted by the high-speed rail construction of track-laying CPⅢ measurement method,In the horizontal displacement measurement of the subway,On how to deploy CPⅢpoint in the subway,how to measure and data processing is discussed,Type CPⅢ measurement has been put forward a new method for the subway horizontal displacement monitoring methods.The purpose of this study is to use the CPⅢ method for horizontal displacement monitoring of shenyang metro line 2,Through the investigation of the site environment,According to the corresponding regulations of the state,Optimize the CPIII method improvement.In the process of inquiry,To verify the feasibility of this optimization method,The author on the site layout CP III control network,And data collection in the foreign industry,The feasibility of this method is discussed by comparison and analysis of the data.This method is applicable to the monitoring of linear metro in small area.And the construction of the existing orbit,So,This method can be applied to the horizontal displacement monitoring of shenyang metro line 2.In the process of understanding the data,To meet the professional demand of subway data processing,This article designed a set of processing software using C#language.The software is based on the measurement of adjustment.Through the established CPⅢ data processing model,Language editing,To complete the core part of the data solution,The design software has the characteristics of convenient import data,convenient operation and real-time control of precision.The development of the function of the system,Very suitable for based on CPⅢ measurement method of total station monitoring applications,Is more convenient than commonly used adjustment software,Not only can the foreign data be controlled,Intuitively find out the disqualified data,but also it can be automatically adjusted,To avoid complicated calculations,This software is very convenient in this area,But there are a lot of drawbacks to this software,It is necessary for the relevant personnel to continuously improve and make the software more convenient.This paper calculates the adjustment of data,And you can see,The CPⅢ measuring method in monitoring the subway is completely feasible,The method is simple and operable,and the measured data is accurate.High precision,easy to operate and other advantages,In the monitoring work,a new approach is proposed,which also provides favorable data for scientific research.
