阿穆尔公路变形演化的永久冻土因素分析(英文)

A permafrost factor in the development of deformations on the Amur Highway

工程研究的主要目标是获得有关自然条件下季节融化层信息;找出下方道路路基冻土的组成和性质;研究堤岸基础土壤(解冻和冷冻)的热状况和识别配置技术以及融区的厚度;分析融区和道路变形之间的连接。阿穆尔公路的成岩基地研究采用了冻土地质工程监测手段。根据所获得的结果显示,多年冻土的自然技术动态区域概况已经形成。研究发现了永久冻土层的高含冰量和融区厚度的道路路堤高度,同时建立了底层土壤的组成和水含量的关系。相对于该地区的自然环境,指出了在自然条件下的全球区域气候变化中高含冰量冻土的大贯量。

The main objectives of the engineering geocryological research are：to obtain information con-cerning the seasonally thawed layer under natural conditions;to identify the composition and properties of permafrost beneath the road embankment;to study the thermal regime of the embankment and underlying soils （ thawed and frozen ）; to identify the configuration and thickness of technogenic taliks; to estimate the connection between taliks and road deformations .The lithogenic base of the Amur Highway has been studied by means of an engineering geocryological monitoring method .Based on the results obtained , a regional overview of the natural and technogenic dynamics of permafrost has been formed .The research has revealed high ice content of the permafrost .A relation of talik thickness beneath the road to embank-ment height, as well as to composition and water content （iciness） of the underlying soils has been estab-lished.A high inertia of ice-rich permafrost under natural conditions relative to other components of the region＇s natural environment due to global and regional climate changes has been noted .
