在东北地区,冬季降雪和积雪常被风吹刮到铁路线路上,严重影响行车。沈阳铁路局管内的通霍线沿线历年来多次发生雪害,2010年12月K247路堑雪害甚至导致行车中断72h。为了根治该处雪害,根据现场实际情况、地区自然特征系统分析了雪害成因,结合气候、地质、材料经综合分析采用了多道透风翼墙式挡雪墙方案进行整治,并对挡雪墙的墙高、基础类型及尺寸、设置道数、挡雪墙与铁路的距离的参数进行理论分析,而且提出了挡雪墙施工的具体要求。
In the northeast, winter snowfall and snow are often blown to the railway lines by the wind, seriously affecting traffic. The snow damage occurred many times along the Tonghuai Line of the Shenyang Railway Administration over the years. In December 2010, snow damage on the K247 road even caused an interruption of traffic for 72 hours. In order to cure the snow damage in this area, according to the actual situation in the area, the natural characteristics of the region were systematically analyzed for the causes of snow damage. According to the comprehensive analysis of the climate, geology and materials, a multi-channel air-permeable wing wall-type snow wall was used for remediation. Wall height, foundation type and size, setting number of road, the distance between the snow wall and the railway, and put forward the specific requirements of snow wall construction.
