对山西省铁路2006-2015年规划的设想

IMAGING 2006-2015 PROFECT ON SHANXI RAILWAY

山西省是我国最重要的能源重化工基地,被誉为“煤海之乡”。铁路对于山西晋煤外运有着举足轻重的关键作用。经过多年的建设,山西铁路网已初步形成,国铁干线从北到南为“一纵八横”格局,形成了北、中、南三大运输通道;地方铁路的支线建设,也已初具规模。面对国家经济建设对晋煤外运的迫切需求,山西铁路的设备能力现状仍处于被动应付的窘迫局面。面对国家经济建设的迫切需求,山西省政府、铁道部和太原铁路局对山西的铁路建设规划了宏伟的蓝图, 一个铁路建设的新高潮正在山西形成。本文通过对山西国铁干线运输通道和地方铁路发展现状的分析,介绍了山西省铁路建设情况和2006—2015年规划设想。

The site of Shenzhen West Corridor Port was neritic zone and oyster land with lots of 7.0-24.0m mud and silt clay.The seae mbankments in east and south were at deep marine zone with great thickness of mud.Therefore,it was difficult to treat subgrade in soft soil zone.The different methods were proposed for treat the subgrade in soft soil zone because of the complexity of the engineering of filling sea and treating subgrade for Shenzhen West Corridor.To the outside sea embankments in east and south,they were filled by stones and treated by the method of explosive drain mud,along with strong consolidation.To the subgrade in soft soil zone within yard plateau,it was treated by the method of plastic drainage plate along with method of stockpile loading pre-pressure for drain water and consolidation.To the insulation embankment and transition zone between sea embankment and yard plateau,they were reinforced by sand pile.The bodies of insulation embankment and sea embankment were treated by strong consolidation.The practices show the application of the methods mentioned above are successful and worth being applied widely.
