卅多年来我们在东北大小兴安岭多年冻土地区修建了两千多公里的铁路,而这个地区不良工程地质现象以冰椎、冰丘对铁路建筑物造成的破坏最为严重。现就其对铁路建筑物造成的危害与防治,以及在冰椎、冰丘地区开展铁路工程地质勘察工作阐述如下。一、冰椎、冰丘对铁路工程造成的危害及原因分析冰椎、冰丘是多年冻土地区特殊的物理地质现象,不管是冻结状态或是融化状态,都给铁路建筑物带来破坏,而其危害性最为
卅 Over the years we have built more than 2,000 kilometers of railways in permafrost areas in the Greater Xing’an Mountains in Northeast China, and the bad engineering geological phenomena in this area have caused the most serious damage to railway structures with ice spars and ice hilly. Now on its harm to the railway structures and prevention and control, as well as in ice, ice hilly region to carry out geological survey of railway engineering are described below. First, the ice vertebral, ice hurricane damage caused by the railway project and its causes Bingli, ice hilly area is a special physical geology phenomenon, whether it is frozen or melted state, have brought damage to the railway buildings, And its most harmful
