| 摘 要： | 路基冻害严重影响了铁路提速，相关部门曾用过一些措施处理，但效果不明显。介绍以新型土工合成材料软式透水管整治兰新铁路路基冻害，通过对现场实测路基含水率、路基冻胀量及路基地温变化的分析表明，软式透水管在路基中具有通风、疏干排水等的作用，在抑制路基冻胀方面的效果很显著。

| Abstract: | Subgrade freezing damage seriously influenced railway speed-raising.The corresponding department ever took some measures to treat the damage,but the effect was not satisfactory.In this paper,flexible permeable hose made by the new type geo-synthetics is introduced to treat subgrade freezing damage in Lanzhou-Xinjiang Railway.Through analyzing the measured water content,frost heaving amount and ground temperature change in relation to subgrade,it is shown that flexible permeable hose works for good ventilati... |
