铁路线路爆炸案件现场勘验研究

Studies on Inspection of the Scence of Explosion Cases on Railway Line

铁路线路爆炸是反映铁路线路爆炸发生原因、过程和结果的物质基础。铁路线路爆炸案件现场特殊性是由铁路的行业性、爆炸的特性和铁路在社会交通中的重要地位所决定的。铁路线路爆炸现场的特点 :1.现场存留从属于线路开通 ;2 .炸点通常为炸坑、轨断或轨变 ;3.线—车现场构成的特殊性 (车底爆炸形成下压 ) ;4 .爆炸物证受到地形地貌影响突出 ;5 .现场位置常为线路偏僻要害处。铁路线路爆炸现场勘验的重点 :1.判定炸点 ;2 .推断爆炸装置 ;3.估算炸药重量 ;4 .确定爆炸性质 ;5 .分析现场环境格局 ;6 .判定犯罪嫌疑人。

Explosion on railway line is the basis of the reflection of its cause,process and result.The specific characteristics of the scene of explosion cases on railway line depend on the trade of railway,characteristics of explosion and the key role played by railway.The characterstics of the scene are:1.the preservation of scene is subordinate to the reopen of the line;2.explosive spots usually are explosive spots,broken rails or deformed rails;3.the pecularity of line-train scene,i.e,the explosion under the train presses dows-ward;4.the material evidence of explosion is greatly influenced by topography;5.the scene often locates in the remote but vital part.The focal points of the inspection are:1.to judge the explosive spot;2.to infer the explosive device;3.to estimate the explosive weight;4.to decide the explosive nature;5.to analyze the situation of the scene;6.to judge the suspect.
