【Abstract】 By analyzing the Karst collapse and settlement in the construction of mountainous railway,four basic characteristics are brought forward and listed as follows:human activities,concomitant,development and wide. The analysis also indicates that the influence of Karst collapse and settlement on resources,ecology and society is serious.Besides,rapid change of hydrodynamic field is considered as the main factors which results in Karst collapse and settlement in the construction of mountainous railway.更多还原
