The sustainable development is our country's important developmental The railway transportation transports in our country holds the important status， the railway transportation has a sustainable development question Railroad's sustainable development， on the one hand must with the nature， the environment， the resources and so on intercoordination， realize the traditional sustainable development; On the other hand must seek own economical and the benefit high development， realizes the business economic sustainable This article take achieves the railroad Limited liability company as an example， has enumerated the sustainable development from two aspects in its company's utilization， has unfolded the sustainable development importance， simultaneously has also given some this article through to reaches the vehicle railroad Limited liability company's condition to carry on the analysis， analyzes restricts this company sustainable development existence subject matter: the electrification transformation is not very thorough; freight transportation resource development insufficiency; rail line plans saves is not very reasonable; traditional marketing pattern; sole operation pattern; the shipping mass and the efficiency cannot guarantee From this， may also reflect our country railway transportation existence some And how to overcome these insufficiencies， swept clean this company sustainable development the barrier to put forward several proposals: carries on the company entire line the electrification transformation; develops along the route the potential market positively; the centralism superiority， increases the propaganda dynamics; carries on diverse the management; the improvement service， speeds up the vehicles appropriation， sets up the good high quality 下个阿里巴巴贸易通就可以翻译了 绝对没问题的 你可以自己去尝试下 我论文里的翻译就这样弄的
Abstract: the paper analyses the existing in the railway roadbed disease are classified， analyzes all kinds of railway roadbed disease occurs， this paper introduces the mechanism of roadbed disease detection method， and points out that the various types of clear roadbed disease and formation mechanism， and the accurate detection is railway roadbed disease prevention and effective governance Article embankment is band structure engineering， the geological conditions along through the difference is bigger， packing is also not even， and many areas in expansive soil， the red clay， soft rock weathering residual soil underlying engineering properties of soil， and the bad by geography and climate change affects， and because of all the technical level， economic conditions and the construction of the reasons of the mechanical equipment， China's railway roadbed design usually adopts low technical standard， the construction quality often lax， leading to various requirements of railway and become a bed disease wide distribution， management difficult， multiple strong disease， and in recent years with the speed of the train and heavy of subgrade stress level， Distribution condition and functions of the significant Because both railway roadbed design capacity， train speed in smaller after the dynamic stress caused by load under various diseases， leading to produce， or make already existent diseases more serious and the serious influence the safety operation of the So understand the type of disease and its occurrence mechanism， and carries on the practical detection， the protection and management of subgrade is very Keywords: railway roadbed， disease， mechanism， detection
