中俄东线黑龙江段地质灾害的特征及危险性

Characteristics and risk of geological disaster along China-Russia Eastern Gas Pipeline

  • 摘要: 通过收集中俄东线天然气管道黑龙江段沿线地质地貌、区域稳定性、地震活动等资料,结合实地踏勘,识别出管道沿线共发育78个潜在地质灾害点和6种地质灾害类型(冻土冻融、河道塌岸、崩塌、水土侵蚀、盐渍土化学腐蚀与盐胀、滑坡)。在识别管道沿线地质灾害的基础上,对管道沿线地质灾害的分布规律进行了研究,分析了地质灾害的发育情况和危险性,提出了相应的防治措施。研究表明:中俄东线天然气管道黑龙江段沿线地形较平缓,地质构造稳定,断裂及地震活动不发育,整体地质灾害发育较少,其中管道沿线地貌及年平均温度是影响不同类型地质灾害分布的主要因素,而管道沿线主要地质灾害是冻土冻融和河道塌岸,地质灾害危险性均较小。

     

    Abstract: In this paper, field investigation was carried out along the China-Russia Eastern Gas Pipeline in Heilongjiang section and its geomorphology, regional stability and seismic activity data were collected. And accordingly, 78 potential geological disaster points and 6 types of geological disaster(i.e., freezing and thawing of frozen soil, river bank collapse, collapse, soil erosion, chemical corrosion and salt swelling of saline soil, and landslide) are identified along the pipeline. Based on the identification result of geological disasters, their distribution laws were studied, their development situations and risks were analyzed, and the preventive measures were proposed correspondingly. It is shown that along the Heilongjiang section of the China-Russia Eastern Gas Pipeline, it is characterized by gentle landform, stable geological structure, undeveloped seismic and tectonic activities and generally less developed geological disaster. The landforms and annual average temperature along the pipeline are the main factors effecting the distribution of different types of geological disaster. The main geological disaster along this pipeline section are frozen swelling, freezing and thawing of frozen soil and river bank collapse, and their risk is small.
