小兴安岭地区的多年退化性冻土与伊嘉公路五汤段冻土试验的研究

黑龙江省小兴安岭地区是我国高纬度多年退化性冻土主要分布地区之一。小兴安岭多年退化性冻土属高温多年冻土不稳定冻土地质类型,多年冻土的热融沉对路基的影响,一是稳定性问题,二是变形问题,这是工程地质中的技术难题。本文主要探讨分析小兴安岭地区多年退化性冻土的分布和特征等问题,以及多年退化性冻土试验段的试验情况,试图加深探讨对多年退化性冻土的认识,研究探索处理多年退化性冻土的技术,这将对保证工程质量和降低工程造价具有重要的意义。

The research about degenerative frozen soil for ages at the Xiaoxinganling region and frozen soil test at the Wuying - Tangwanghe section of the Yijia highway

The Xiaoxinganling region is one of the primary distribution region of degenerative frozen soil for ages at high latitude in our country.This paper primary discusses distribution and characteristic of degenerative frozen soil for ages at the Xiaoxinganling region which is belongs to high temperature frozen soil for ages and unstable frozen soil geology style.And it also expatiates instance of test at the working section,discusses understanding and technology of degenerative frozen soil for ages.The meaning is to ensure quality of construction and to reduce cost of construction.
